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.
