Looking for a little trouble shooting help here. I have a lightly used 2061 head into a 2061 cab through a Marshall power attenuator.
My problem is that while playing, midsong I suffered a marked drop in volume. The amp works fine, but the volume is greatly decreased and the response is earlier distortion.
I changed the output tubes without improvement.
Any clues as to how to trouble shoot it? I don't do much beyond changing tubes and biasing.
Thanks

I'm no amp tech, I'm sure someone else will chime in. I do know that the 2061's have had a lot of transformer problems for a new amp. Not sure if a tranny problem could cause the volume drop?

I have blown 3 trannys on mine, I have not used an attenuator or mismatched impedance. My amp is on its way back to Marshall as we speak.

ouch is right......That was one of the symptoms when my second one blew.

So if anyone really wants one of these heads might be a good idea to get one soon and put in a Mercurey Magnetics O.T.

Marshall must be spending a lot of $$ on shipping, parts, labor...to continue to repair these. The number of posts here and in other forums is staggering really. They must be planning to either upgrade that spec or discontinue the model. They can't possibly continue like this!??!

I've heard good things about the Mercury Magnetics OTs.
Any referrals to a good tech to do the work in the Northern IL, Chicago area?
