The serial number is the number stamped into the back plate below where it says SPEAKERS.

Oh, by the way, the headshell wood is Peruvian Walnut. That's what that species of wood is known as. I don't know its actual species name.

Apparently it's difficult to legally import. I was told by the wood supplier I bought it from that they won't be able to get any more of it.

I disagree with the notion that an acoustic guitar is the best choice for beginners. I think every player should have one, but the best choice for a beginner is an easy playing guitar with comfortable action, good setup, and is the one that the player likes and wants. If you dream only of electric g...

Very high gain/drive levels are not conducive to controlling your tone with your guitar's volume control. You might note that those amps that are best known for that trick are all medium or lower gain by modern standards. If you have so much gain that the slightest movement of the string is amplifie...

Those voltages seem to be about right for me. That's with the amp operating and all tubes in their sockets, right? As for the preamp tubes running hot, Mark IIs are known for that. While I can change out a preamp tube with the amp in standby without getting burned on a LOT of amps, on a Mark II and ...

JD probably hit it in one. If a coupling cap shorts (it'll be a .1 uF 600 volt orange drop) then the tubes on that side of the OT will lose bias and will red plate. It's recommend to replace both coupling caps as as pair.

Been there, done that.

Check out the bass control in the clean channel. It should be effective there, no doubt about it. In the lead channel it will be less effective. Basically it'll just control how much bass gets into the clipping stage. The tone controls are pre-distortion. The graphic EQ is post distortion. So, tone ...

I just want to make note of the fact that speaker and cabinet selection makes a huge impact on tone, always. The tonal difference between a Mark IIA, Mark IIB, Mark IIC, Mark IIC+, Mark IIC++, Mark III black dot, Mark III black stripe, Mark III blue stripe, Mark III purple stripe, Mark III green str...

I used to own Mark IIA serial number 3116. Yes, the clean master (master 1) functions as a volume limiter when in the lead mode. To get louder by turning up the lead master, master 1 has to be high enough to allow it. It is best to think of master 1 as a limiter. Or as the TRUE master volume on the ...

I am the former owner of this amp and the maker of that custom headshell! I am very happy that you are thrilled with it! If at some point in the future you get tired of it, contact me, and I MAY at that time be willing to buy it back. I had to part with it for financial reasons, not because I hated ...

Sounds like somebody's mixed up here. The EQ knobs aren't 1" across. They're not rotary! If you need the knobs for the EQ sliders the ones Mesa sells today fit just fine and they are very nearly the same size as the originals. There were only ever two versions of those knobs, so if someone is sellin...

Just look at the silvering on the inside of the tube. If it's turned white the glass broke, the vacuum is lost, and the tube is dead.

If the silvering is still silver, put on a socket saver and put that tube back in service. Make sure you position the socket saver correctly.

More likely the problem is a preamp tube. Even weak power tubes don't drop their power output by THAT much. Swap around some preamp tubes and you'll soon know which ones are suspect. Has that amp been serviced? It's old enough that it should have been recapped by now. If not, it's due..and then some.
