The Boogie Board

I don't like overdrive/distortion pedals. If the amp's own overdrive doesn't kick ass, it's not an amp that I want. I would never call myself a great guitarist but I follow the Ted Nugent school of effects chains: Nothing between the guitar and my amp but a straight cord and no noise toys to mess up...

Because the outer pair of sockets is the only pair that can take either 6L6 types or EL34 types, it's obvious that if your favorite tubes are EL34s, they need to be in the outer socket pair. But if they're 6L6 types, it literally makes no difference at all whether you choose the inner pair or the ou...

I found it! Yes, it's in great shape, known good. Part number 562050.

Yes they are. But they're extremely busy and probably understaffed for the amount of business they have to handle.

Be sure to leave a message. They'll call you back.

Better yet, contact them via email.

I have one that came out of a Rocket 44. It's 4x EL84 tubes. It's in perfect working order. Would that interest you?

Consider approaching Mesa about it. They might want to buy some from you for them to stock for repairs.

That might help you to get the per-piece cost down to something much less painful.

Contact Mesa and ask for a repair estimate on that amp based on the presumption that it needs one OT at the least. Use that estimate as a reference. Any competent tech likely won't charge more than Mesa. Get the transformer from Mesa. Don't mess around with other sources. The Mesa one will be correc...

I'm reasonably sure that you'd need a different output transformer when changing between simulclass and 100 watt models.

Try the green channel in the pushed mode. I actually find it to be the overdrive tone I like best out of the amp. I'm not a big fan of bright fizzy sounding distortion. The red channel and the orange channel are nearly identical. Only the presence pot value is different, and any decent amp tech can ...

No, MB written in sharpie under the power cord means the amp was put through test by Mike Bendinelli. Who tested MOST Mesas in the Mark series.

A smaller number have RS written instead of MB. RS means, yes, Randall Smith.

Use Deoxit D5 or other products in the Deoxit line. They're MADE for the job. Even Mike B. would approve of their usage.

As for the question about headroom changes after working on that 50/50 amp, I'd bet long odds that the change is due to having replaced worn out filter caps. Those are your power reserve for high demands, and when the caps are done they will not store the energy they used to. I picked up a Simul-Cla...

A "fetron" is a solid state replacement device that was made for a variety of vacuum tubes. They were made by TRW and employ one or more JFETs as amplification and switching devices. They plug right into the tube socket but you need to be sure that you have the RIGHT fetron for the right tube replac...

It's plywood. Good plywood. Probably birch. Nothing that looks amazing if given a finish.

Try a different amp with that cabinet. Did you have the amp cranked? A 150 watt amp puts out over 300 watts if the power stage is saturating. Marshall's spec for a "100 watt" 1959 Super Lead from the early 70s was 170 watts RMS at 10 percent distortion. Fender listed my 180 watt Super Twin Reverb at...
