It is all good. I have opened up completely to the TC-50 but it seems more like the little brother or son to the RA100 if matched the appropriate cabs. Also with the RA100, tube choice is key for this amp. TC-50 is awesome with the stock tubes (but I changed V3 to SPAX7 and oops lost the original when I put stock tubes into the RA). Heck the SPAX7 is essentially the same tube anyway, just selected for specific character vs did it pass the go, no-go test. (I am being crude for simplicity and not claiming issue with the way Mesa tests tubes.).

The feature set of the TC-50 is the crown jewel. Still I like my RA100 actually both of them. The TC-50 is just a welcome new addition. I did list the tubes I prefer in the RA100 in a different thread regarding the TC-50. No plans on experimenting with the TC-50 to any extent but did run the SED =C= EL34 for a short period. Seems the Mesa branded EL34 sounded about the same. I do not get the same response with the same tubes in the RA100 probably due to the supply and power amp section. May have to hear how the same preamp tubes will sound in the Combo pushing the Mullard RI EL34. Not sure if I tried that mix but may have. I have the extra tubes to do it since I pulled all of them out of the Mark V and found something better that works with majority stock tubes. V4 change to 12AT7 JAN type = awesome for the CH3 circuit and does not effect the other two channels.

I'm anxious to see what you think of it with the Creamback. I'd especially like to try one with a greenback type speaker to see how Brit it can be, so greenback, Creamback M, Private Jack or... (jackpot) a Scumback M!

The creamback had too much of a vintage voice. Seemed to not complement the amp but I do like them with the RAcombo for some reason. The versions have in the RA100 Combo are the 75version and not the 65 versions as they do not sound the same. I believe the 65s are a bit brighter in tone than the 75. RA combo would fall into partially open or ported back vs open or closed and the actual cabinet size may be a bit smaller than the Horizontal cab. Sooner or later I will get the loose creambacks into the traditional size egnator 412 cab and see how they sound in the smaller cabinet. I did like them in the OS recto cab but favored the EV paper weights a bit more for the style of music I like to play more often than the vintage style and they sounded better with the Roadster and JP-2C for that purpose alone. CB12H75 were great though. Spent the money so why not get them installed into something.

So far the best option for this amp was the Vertical 212. Horizontal 212 should sound similar but I have not tried that one yet.

Have to think of the TC-50 this way, if Mesa made a lunch box sized amp that used standard power tubes (not the mini EL84) what would it be? TC-50 would be it. Scaled down version of the RA but with added features. Loud enough to be deafening and yet can be dialed down using the master control and still get the same character out of the preamp and just a little over bedroom level. Perhaps that is why I held onto the Mark V as I can run it at 90W and drop the master control and still get great sounds. Yea, 45W and 10W will do that too. JP-2C, it is a beast and for gest results it needs more energy to feed it. Just like the Roadster and RA100, sweet spot is near deafening volume but can be dialed down to some extent before altering tone and dominating in one frequency. Sure Roadster, RA100 and the JP-2C have half power features. RA100 also has the power soak that I used once in a while.

On a larger scale, OS Recto 412 with stock speakers was okay but did loose some tightness, loud as well. On the flip side I have an older OS Recto 412 I refitted with the EV black labels and that was deafening. I actually like the V30 with the TC-50.

That's good because I already have a 2x12 vertical recto cab (and the 1x12 recto cab). Just wondered what the TC would be like with an M type speaker or two or four. 8)

Unfortuantely I do not have an M type speaker, or do I ? Nope. I have the H type. I do like the sound of Greenbacks from what I have heard walking though the local guitar shops when someone may be playing through one of the Vox AC30. you have to stop and listen and wow that does sound great.

I generally stick with the ratings that provide enough overhead to reduce burning up the voice coil. Lessen learned too many times. Fried a WGS Black Hawk HP100, and possibly the Celestion Cream 90W alnico when I ran the JP-2C though it. that speaker was super hot in temp after I started smelling something burning. Once that happens speaker will not sound the same. The RMS peak of the JP2C will reach 150W on my attenuator. The Mark V has an RMS peak of 110W. Not sure if the attenuator is all that accurate. However, it remains stable at 100W with the Roadster going full bore.

The M types represent Brit tone to me. Many people lately have loved the Friedman 2x12 and it mixes a greenback with a V30. A v30 can overpower a greenback if you're not careful. Scumback has his V30s and Greenback types within 2dB of each other so that they mix well in the same cab. I've had good luck with mixing an Emi Private Jack (greenback type) and Governor (V30 type).

But many of your "high gain Marshall" type amps use all greenbacks or higher powered greenback types, like the EVH cab for the 5150. So I've always wondered how a RA100, Stiletto or now TC50 would sound with that type cab. I'm sure it would push it a little close to "M-land."

The first time I demo'd the TC50 the head was hooked up through a Marshall reissue 4x12, I think the 1960AHW. It sounded great. I switched to a recto vertical 2x12 because that's what I generally play through and it was tough on the ears by comparison. The Marshall can was more balanced and smooth, the recto was more high-mid focused and crunchy.

I have no doubt that the TC had been dialed in for the 4x12, but it may also be that the G12H30 pairs well with it. A pair of them would come in at just enough power handling.

Last night I did not play through any amp. Instead, I decided to read through the TC-50 manual. Yeah, day late and a dollar short. After reading the booklet, I decided to install a new Mesa 12AX7 to replace the SPAX7 I installed into V3 thinking it would kill the unexpected rebound of the Mark V story. Well no need to worry as the manual covers this topic so this may be expected depending what you dialed in for that particular channel.

I did try taking the treble out as suggested in the manual and bumped up the midrange. Sounds great. I sort of like the treble where I had. Now which one is my favorite channel..... tough to decide as all three have great tones to offer. Definitely a worthy amp to consider in light of my first impression.

I did manage to make a recording of both the RA and the TC-50. I used the RA100 combo for two reasons, what the open back V30 cab sounds like, changed speakers back to the G12H75 Cream backs, TC-50 with Cream back and then Vert 212 with V30. For some reason I do not notice the difference between the V30 and the Cream backs. It must be the preamp in the mixer as I did not record direct into the Tascam DP-32SD recorder. Mixer I used was a Soundcraft Sig 22 MTK. I also used a pair of drum mics (Audix D2) on the cab and an NT1-A as reference about 6ft from the amp. My guitar playing skills may not be up to par as most of you but at least you get a home recoding version that may be good or bad, I will leave it up to you.

What happed to my JP-2C? On that regard I have not seen the Roadster in quite a while now (I see it every day I leave for work as I have to pass though the studio or living room to leave thought the side entrance but it has its cover on it now). Both amps sitting idle with covers on them. Tubes are cold and the bottom of the speaker cones are filling up with fine dust particles. I think the TC-50 has taken over......

Love the 6V6 tubes but used them for a short period and went back to the EL34. This amp sounds better every day I use it. I still have difficulty trying to place the general tone. CH3 may tread on some Recto territory and CH2 may step into Mark tones. Perhaps it is an illusion. This amp is amazing in all regards. I recently picked up a used Kiesel guitar with the Ghost Floyd Rose bridge (licensed by GraphTech in agreement with Floyd Rose) it has the acoustic piezo saddles under each string. I had considered it when I ordered my Last Carvin but opted not to get it. Now that I have that feature I am even more impressed with the TC-50. Yesterday I pulled the Fishman Aura preamp out of storage (I use it with my Mexican Martin 12 String as it sound almost as good as a condenser mic). Holly crap, and electric guitar with a locking Floyd Rose sounding like any acoustic guitar of my choice was a treat to behold. Better served up in clean mode without drive. Also without the fishman, the piezo blended with the passive magnetic pickups sounds interesting too even with distortion. Of course I can switch to all passive and disable the piezo. I have not compared this to the Mark V but doubt I would love it as much as the Mark V channel 1 seems to have a low frequency hum with the stock tubes. Could be a diode issue on the 12 Volt supply as I think that is tube heater related. Will also have to try both the JP-2C and Roadster with the new guitar and its features. However the TC-50 is so much fun to play though I feel I do not need anything else.

Since I have had the amp for about a month, it seems to be the one I pick first to play though. Yeah, I have bonded with it and love it. One surprise after the next as it seems to have become a top favorite, even more so than the RA100. Hate to say it but the JP-2C has been covered for a while now. I would play it more if it was sitting on a cabinet. Methinks I need another Vert 212 cab, but I keep telling that other voice in my head to shut up. But to persuade me into realizing that two of the vert 212 cabs would make a killer 412 but it would be a 4 ohm load. I did run the vertical and horizontal though the amp and was blown away more than I was with the OS Recto 412 cab by itself. A second Vertical 212 would be worth buying vs getting a 1x12 wide body cab. I may just do that....

For a really cool thing, I ran the TC-50 in parallel to the Roadster. Now that was awesome. Have not tried the JP or Mark V in parallel yet. Had to fire up the Roadster as it was also sitting cold in the studio. My memory of the tone did not serve me well as it sounds nothing like the TC-50. However when blended together was just incredible and I could not stop playing.

Always interesting and fun reading your thoughts. I have a vertical 2x12 recto and a couple of horizontal 2x12 rectos. I've been considering putting a cream back in the vertical to try a mix with the V30.

I put 6L6s in the TC-50 just to try it out but I need to put the EL-34s back in to see how the differences feel. I know they're both awesome though.

I think the TC-50 really does have its own sound. It doesn't sound quite like anything else I can think of. It just seems to have its own great sound.

Blending a Creamback with the V30.. the V30 will win. I have tried that with my old OS 412 Recto when I got the Creambacks to stuff into it. I eventually went back to the EV speaker in that cabinet and moved the Crembacks into the traditional sized Egnator cab just to see if the cabinet size would make a difference. I have notices that the Creambacks will not be as loud as the V30 and may be due to the difference in frequency response. When mixing in the same cabinet all you will hear is the V30 even though the Creamback is pushing air too. However if they are loaded into different cabinets it sounds better. The same would apply to the EV as I had tried a mix of those with V30. V30 dominated that arrangement too as the sensitivity of the V30 is high relative to the other speakers. The larger voice coil of the EV sounded like there was a response time differential to the V30 which sounded interesting...

What I thing would sound great but too expensive for me to want to try it...... Celesiton Crème 90W alnico either blended with V30 or replace both in one of my 212 cabs with the 90W crème..... ouch. I can buy another vert 212 for that which I may just do so as I like to play the JP just as much as the TC-50 but swapping heads on one cab is okay but would rather have the ability to run the two amps in stereo. I prefer the v212 over the H212 but had to get the H to try it with my other amps (still and awesome cabinet).

To be honest, I ran both the V212 and the H212 in parallel and that was huge and powerful and made the OS Recto 412 sound weak. I did this with the JP-2C but have not tried it with the TC-50. I am actually surprised how well the TC-50 sounded with the EV speaker. It may not have been spectacular like when driven by a Rectifier or Mark amp but it did not drown out with low end drone like the RA100 tended to do. V30 seems to be king with the RA. The TC-50 does well with other speakers like the cream back especially if the cab is open back like the RA100 combo. for some time ever since I got my first OS Recto cab I just did not like the V30 as much (My Mark III had the EVM12 Black Shadow which must have tainted my brain). It was not until I got my 2nd OS Recto cab to match the RA100 head that I really bonded with the V30. The V212 made me like V30 even more. Perfect cabinet for the V30. Not sure how it would sound with other speakers in it.

I have been playing mine ever since I got it. Yes it has its own thing going on but also is quite similar to the RA100. The more use I get on the EL34 the better the amp sounds. reduction in the treble control doe help too on Hi/Lo. The manual helped to describe the relation on the tone controls a bit better but I still set my settings with my eyes first and not my ears as is the way it should be done.

If you want to get the 6L6 Markish tone from the amp, get a pair of 6V6. That just blew me away but not as loud as it is a half power reduction in output.

If you had more than one amp with their own speaker cab, running the TC-50 in stereo or parallel can be a thrill. I blended the Roadster and the TC-50 and was impressed with the mix. Will have to try it with the JP or Mark amp. It does sound extremely awesome with the RA though.

I was considering the Creamback 65 simply because that's what Peavey put in the Invective cabinet. That's a pine box and surely has different dimensions but interesting. I may give it a shot for the heck of it.

I actually was wanting more of a recto-ish tone in channel 3. Also I was kind of wanting a warm Fenderish or Lonestarish clean in channel 1. I think the 6L6s and putting Ch 1 in drive mode got me in that territory.

With the Precision Drive in front of Ch 2, and an MXR 6-band EQ in the loop the TC-50, which I already loved, has blossomed. Well, mostly. I did have to crank the treble back a lot because the PD seems to increase it significantly. That's fine because I can dial it back at the amp, the PD, and/or the EQ.

I am using the TC through a vertical 2x12 but also have a pair of horizontal 2x12s. I can run the 5:25 through one of those and that's pretty awesome in stereo. I'm not using it that way right now though. Just using the TC in mono. I've been GASing for a 5150/6505 for a while now but the clean channel isn't really what I wanted. I could run multiple amps but would rather run a single versatile amp if possible. The problem is I want that amp to be capable of everything from jazz to pop to blues to rock to metal. The TC-50 can absolutely cover all that ground and do it well.

With that said I'm still GASing for those 5150 high gain tones. There's just something about them. So the odds are pretty good I'll be grabbing an Invective at some point. If the clean channel is as good as is advertised, and if it takes pedals as well as advertised, it could be just what the doctor ordered. And I just imagine running that in stereo with the TC-50. :twisted:
