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.

Re: NAD: Multi-Watt Dual Rectifier

The MWDR to me sounds like CH2 and CH3 are identical twins. No change in voice or tone between the two like there is with the Roadster when switching between 3 and 4. Love the amp in spongy power mode with tube tracking. Amp still remains tight. I should look and see what Rectifier tubes are install...

Re: TC-100 vs Rectifier - Questions

Another late response. Today I pitted the MWDR against the TC-100 just to see what is similar and different other than the obvious (EL34 vs 6L6). Since the MWDR does fit on top of the Vertical 212 (rubber feet will sit but head is much wider than the cab) Well a surprise was to await me on the clean...

Re: TC-100 vs Rectifier - Questions

BUMP….. I know this is late... been a while since I have been on. Thought I had posted to this thread but for some reason not there... sorry for the late response. Have both TC-50 and TC-100. Sure, Mesa knocked it out of the park with this series. TC-100 would be more favored for the ample bass. I g...

Re: Roadster Reverb Issue

I have tried the channel switching while in standby. Perhaps I am not doing it enough times. I generally cycle the channels as well as the mute after I take it out of standby following a cold start. After that I do not get pops. Good to hear you resolved your reverb issue. The white wire does not ha...

Re: NAD: Multi-Watt Dual Rectifier

After having this amp for a while now, I am still impressed with it. I am now considering getting another OS Recto slant front 412 cab so I do not have to keep the RA100 off of its pedestal. The grey and black jute cab looks much better with the RA100 sitting on top since they match. I can get by wi...
