hey to all

i stumbled upon this sight while trying to find someone who is best qualified to overhaul/repair & tune up my MM 112-65 (it's practically a cherry). i would like to get it back to spec as much as possible as it has given me years of trouble free playing and i am too used to the tone to like anything else (well... under $1000 anyway).

i hope someone can help or point me in the right direction. this is a cool sight but i am not interested in doing the work myself.

have a blessed holiday

man this thing sounds better every day now that i am playing it again... it must have been sick for a long time and i just didn't realize it.

i really like the Svetlana EL34 tubes with the GE 12ax7 in the pre section. i had been using Sovtechs all the way until now.

thanks again for the repair and the advice!

ok almost 2 years of regular play and the tubes finally went south... amp getting real noisy.

i popped in a new matched set of Electro-Harmonix EL34s and re-set the bias to 0.5 dcV and i'm good to go!

I really appreciate your continued diary about your experiences with your amp! This is the kind of real-world experience that is hard to come by on many subjects, especially Music Man amplifiers.

What did Terry do to your amp when you sent it to him? You certainly got a quick turn-around on the repair!

sorry i never responded steve - but here it is 2010 and the amp is still kicking hard! i'm not real sure all that terry did when he had it? i think he replaced some caps or other minor components - all new tubes and set the bias. i have replaced the tubes in it a few times myself and now know how to set the bias thanks the instructions terry sent me - it really is pretty easy. MM rocks!

Alex-I just noticed that I screwed up your real name-sorry. I've gone in and corrected it. Mike.

still a work horse!

here it is may 2016... and this amp is still kicking butt - without fail - and stronger than ever.

MM... still the best amp out there in my opinion (the original MMs)!

Funny you mention the ORIGNAL

Funny you mention the ORIGNAL MM's. Anybody seen anything of the NEW ones yet? Mike.

still going strong!

Update 2018 (July) - so last March (2017) the tremolo died and several of the pots were getting unacceptably scratchy. I was also possibly (?) interested in having the "FUCHs Mod" done to this amp so I called them to discuss the options. The price was a bit too high to justify the mod but they did have the original optical tremolo chip - so off it went. I don't use the tremolo that often but I want to keep this amp at 100%.

While they had it in the shop Andy emailed me to let me know the tremolo was replaced and running perfect and everything else checked good except the original filter caps (the 2 really big caps) were about shot - so I had him replace those. He installed Nichicon premium caps which are OEM. Turn around time and communication was great, price was about what I expected - fair.

So anyway, it's a 44 year old (100% stock) MM amp and still running like a freight train - you just can't get any better than that!

Awesome to see this site is still up and running!

alex_davis

Yep - still running strong!

I'm pretty sure this amp will long outlive me! I may look into having the speaker rebuilt in the next few years? Maybe for it's 50th bithday?
