Hey guys, not sure if many have had experience with this amp. It gets a bad rep for being cheaply made....and I agree. Mine has broken 2x in the year that I've had it. I would scrap it.....but I honestly like the tone. It evens out my super mid-scooped 6505 and together they create an excellent sound for the type of music I play, so I want to keep it alive.

Anyways the problem. The amp, when you turn up the master volume......its really quiet. I mean when its up to half, my 6505 is beating it at 1.5 on post gain. The Madison has always been quieter but this is ridiculous. also, once the volume gets turned past half it goes DOWN and it starts to get very muddy and dull. Like someone turned the presence from 10 to 0.

So I'm wondering.....is this a major problem? Possibly a transformer? Or could it be just a bad preamp tube? I swapped the power tubes from my 6505 in and it still did the same exact thing so its not a power tube. At least I'd imagine.

anyone have any ideas?

Do a full tube swap. Couldn't hurt.

Not necessarily...you could do that with the preamps first to diagnose if it is a preamp tube problem. But an easier way of doing that is to just tap on preamp tubes (while the amp is on) with the eraser of the pencil. If you hear loud noise, the tube has been compromised.

As for the volume issues, I say it sounds like power tubes, even though you said you swapped them already. Give the preamps a swap though.

So I swapped out all the tubes, preamp and power. None of the preamps were microphonic. One was not working at all but even after replacement it still did not fix my problem.

Upon inspection of the power tubed with the amp on, I noticed some of the power tubes had blue glowing rings on the sides when the master volume was turned up 3/4 or higher. One of them did not do this. Does this indicate any sort of problem?

I believe my problem lies somewhere within the electronics board of the amp unfortunately

any chance i have a bad transformer or cap?
