Re: Triple crown 100 vs Roadster!?

The TC-100 does an excellent job, it is a hard amp to beat until you get to a song that requires a Dual or Triple Rec. I still have plenty of love for my Roadster and it has become a main part of my desired rig setup. However, TC-100 is one of the go-to amps for jam sessions when I have company. Sin...

Re: Roadster (Road King) on steroids

For those interested I did make a video of the Roadster with the new complement of preamp tubes. Note that I was using an oversized 412 cab loaded with EVM12L Black Labels with the Roadster. Also near the end of the video I pulled in the Multi-Watt Dual Rectifier that still has all of its original p...

Re: Roadster (Road King) on steroids

Just a quick note regarding the Multi-Watt Dual Rectifier; I was tube rolling this amp as well but wound up with the stock tubes in the preamp. The Mullard re-issue or Gold Lion B759 reissue would sill work in the phase inverter position. However it will create a low frequency hum in V2 since that t...

Roadster (Road King) on steroids

My interest have picked up considerably with the Roadster ever since I got the Mulit-Watt Dual Rectifier. This happens with me when I get amps of the same family or series as I like to find out where the similarities are and where they differ. Mind you this is not to evaluate which amp is better tha...

Re: NOS 12AX7 tubes for Cathode follower ?

I did get the JAN tubes today. Tried them in the cathode follower positions after I tested them on the Orange VT1000. They definitely brighten up the MWDR considerably in V3 and V4, think the FX loop gained some sound levels. I went back to stock tubes with the MMDR for now. However the Roadster ben...

Re: NOS 12AX7 tubes for Cathode follower ?

Thanks Don, thanks for the reply. I am well aware of the Russian tube issue, but It is always good to express that as others who may read these to be well aware of that issue. I can get some 70's JAN/GE 12AX7WC tubes but was wondering if others may have used that or similar with their rectifier amps...

NOS 12AX7 tubes for Cathode follower ?

Is any body running a NOS 12AX7 in the cathode follower positions in their Dual, Triple Rectifier, Road King II or Roadster? I was looking at comments on NOS tubes at tube Depot, JAN/GE 12AX7WC and noted a comment about use in cathode follower of a Marshall. I know the preamp section is very similar...

Re: Orange launches valve/tube tester

I got around to buying one of the VT1000. It seems to work and I have run through my box of preamp tubes and power tubes. It is not difficult to generate high voltage from a DC supply. A switching step up converter can get a high enough voltage to run the test. However I believe the device works mor...

Re: Using a 12at7 in place of 12ax7 in dual rectifier

The last tube roll I did in the Roadster has me stoked. I have had it this way for a week and I am really satisfied with the end results. No, I did not use the 12AT7 but something similar.... JAN/GE 5751. Have this in V1, Mullard RI long plate 12AX7 in V2 and V6 and all stock everywhere else. This a...

Re: TC-100 vs Rectifier - Questions

It has been a while since I have been running the 412 cabs. I basically forgot how they sounded until I bought a new MWDR. Damn does that sound so good. Then it dawned on me that I never really dove into the TC-100 as much as I should have. I have been glued to the Vertical 212 so much that curiosit...

Re: Mesa Dual Rec Roadster Head- Lost Channel 1/2 AGAIN

You can see what JJ preamp tubes look like in the image on the page or if you click on the 12AX7 tube. They have a wide flat metal plate that gets formed into a flat round disc over both triodes, and then there is also a flat extension with a halo getter above that. They are JJ ECC83s. Those will wo...

Re: Mesa Dual Rec Roadster Head- Lost Channel 1/2 AGAIN

+1 on the cathode follow circuits. Sounds more like V5 may be the culprit if you are using the FX loop in active mode but this issue would be consistent with all 4 channels. You can bypass this circuit completely if you turn off the FX loop function on the back panel. This will also disable the mast...

Re: V1 tube ridicule

I still have the long extended tube shield in the Roadster but did away with the long extension on V1 in my Mark V. You can get tube shield replacements from Mesa's on line store. I bought 10 of them to keep on hand. Also have a lot of amps to keep going so the extra parts are good to have. Even the...

Re: 90 watt Head is 10 watt issue all channels

You may have a weak preamp tube in the phase inverter. Like others have suggested I would start there. Rectifier tube is active all the time but will be bypassed in 90W mode but will still be conducting current some current since the heater is also the cathode but the contributing current is negligi...

Re: Does my Road King need servicing? (video showing potential issue)

I watched the video and have a good understanding of what you are hearing. For piece of mind my Roadster does the exact same thing. I would suspect this to be normal.
