Re: fifty/fifty 1 tube burning red hot.

Sounds like the first tube shorted and took out the screen resistor. Now that socket will damage other tubes you put in there so....don't. Not an uncommon issue in tube amps and not generally difficult or expensive to fix, assuming no other parts were damaged. But yea, you need to take it in to a te...

Re: New Single Rectoverb owner

Most of the tube vendors out there will know what range is OK for your amp. I like Tube Depot, but there are many others (like Doug's, mentioned earlier) that can set you up right. As a reference, Groove Tubes rating #5 is right on the mark, and the folks at Mesa have told me that #4, 5 or 6 are acc...

Re: Triaxis - Lead 1 Red not working

Sorry I did not catch your post sooner... You may have already shipped to Mesa....but... I know those ribbons can be a pain, esp. the older ones that Triaxstasy described. Deoxit was not effective on mine. I removed the crimp on connectors (tricky, but doable) and moved the conn. up the cable about ...

Re: Mark V 25 Problem

One more thing you can try, assuming you have no spare tubes at all..... Rotate all the 12ax7 preamp tubes down one position; move tube from the first socket to the second, second one to the third and so on. Since different stages of the amp work under different parameters (plate voltage, amount of ...

Re: Mesa Boogie Studio .22+

Back then the speaker should have been a Vintage, called a VS12, which was sourced from Eminence. I don't think there was an MC90 yet. Al I'm not at all sure when the MC90 was introduced, but I bought my 22+ in '89 and it came from the dealer with C90 and EQ options. And +1 on the 6l6's. Different ...

Assuming the speaker label is still in tact, the stock speaker will say "Vintage" on it.
The C90 will say "Type MC90" and have a Celestion logo as well.

Either way, with the EQ, it seems like a good price.

Re: Mesa Boogie Studio .22+

Depending on the speaker and the venue size, most would find it easily loud enough. I have the upgrade Celestion C90 in mine, which seems more sensitive (and sounds better, IMO) than the stock speaker that a friend of mine has in his .22+. And an extension cab will up the ante considerably. I have g...

Re: DC5 has blown output transformer, need tech advice

Did it blow a fuse? It could just be power tubes and screen grid resistors. +1!! This is a common failure for tube amps. It is most likely a bad tube shorted and caused the grid resistors to burn up. Usually it will blow the fuse without harming the transformer (usually). If the fuse did not blow, ...

Re: WTB Mesa Rectoverb 50 Manual

I'd imagine that anyone that has the manual also still has the amp...the manuals usually go with the amp if sold. But any commercial print shop could print it out from the .pdf manual file at Mesa's site. They could do a nice binding on it, with some nice covers, and you'd have a professional lookin...

Re: Dual Rectifier change to Triaxis.. good idea?

That thread is not correct. The TX4 board was added at #T1631. The Phat Mod was done on the TX4 board and was standard from serial numbers T5200 - T8279, at which time the TX5 board was introduced. Thanks! I know this is a "late entry" for the post, but do you mean TX5 was added? I have a Triaxis, ...

Re: Mark V 25 Problem

Very possible a preamp tube (generally a 12ax7 type), or even the driver tube (also a 12ax7) for the output tubes. As it's a new amp, it still is under warranty (even if you happened to buy it second hand...warranty is transferable) and Mesa has great service. Give them a call and they will help you...

Re: Rectoverb 50 combo tube question

The wxt's could work but when you order them, you need to specify that they are for a Mesa amp, so you get tubes in the correct bias range.

Most suppliers will know what you need...call and ask. If they don't know or say it does not matter, find another supplier. :wink:

Good luck!

Re: Rectoverb 50 combo speaker question

As long as the total combined impedance is no less than the lowest output of the amp (4 ohm, usually, for Mesa amps), you will have no problem.
And tele twister is right; the Mesa manuals address this in detail. :wink:

Re: Improving Lead Tone on my Roadster

Have you tried swapping any tubes? Especially preamp tubes... Even though they "work" it does not mean one isn't a bit "wimpy". Perhaps get a spare and try swapping out each tube, one at a time, starting with V1. If you want the most gain, I can suggest the Tung-sol reissue 12ax7. I have found them ...
