Pics would be welcomed!
i have the same head, different config:
1982 MB MKIIb 60 watt head, NO simulclass, NO reverb, with graphic EQ.
original owner, i bought it while doing full time road work.
put my order in, paid for it, and had to wait for 6 weeks while they built it!!
LOL, put so many frickin hours on this thing,
and it never failed, not once.
not even when the tubes went bad! it just kept working....
i had it re-capped about 10 years ago, still going strong, it is my main amp for recording now.
Great tubes and don´t get me wrong, the Mallory caps were great - back in ´81.
They are 38 years old and even the best caps getting weak at that age.
I wrote that because I know every time I get one of those for repair I have to change the caps just because they are running at the limit.
I love your amp and it really is a great example of a very clean amp from ´81 esp. being a Mesa.
All the best,
I'll defer to you as I'm no amp tech in anyway, shape or form. I have the parts to build one soon: http://www.strat-talk.com/threads/my-mojotone-studioone-amp-build.509447/
Should I ever need servicing on this I know of an old Boogie specialist in my region. No way I'd attempt a repair unless I was 200% sure of the problem.
Part of the reason for this disassembly is to make me more comfortable in the building process. Not that this was a challenge - it was not. Pure curiosity and I have always wanted to.
Superb! They were able to find NOS caps it seems ... Nice! How do you like the Weber attenuator? I've been looking those over for years.
I did not want any nasty transistors in my Boogie! Think I had the same 6 week wait. Maybe an additional week or two.
To this day I clearly recall the FedEx truck's arrival.
Back together. It powered right up and sounds great. More images to come.
More images all at 1280 max. I can provide the full resolution if anyone wants them.
Yeah, I got a Mesa MK V 25. Brad Gillis was telling me (son’s uncle is the drummer/ singer for Night Ranger) that on the new Mesa’s you can hear a click through the front of the amp when using the footswitch to change channels. Honestly I haven’t had this happen on mine so they must have fixed the problem. I just got the amp a few months ago and I last spoke with Mr. Gillis over a year ago. Is your footswitch quiet?
The condition on yours is amazing. I have a friend with a music store, he sells lots of vintage stuff, who would love to buy your amp. He’s a Mesa dealer. I bought my amp from him.
I am overseas at the minute but I'll post a few when I get back to the states....busy munching sausage rolls in Blighty just now.
Hang on, found this old one on this computer....
No, the footswitch has quite a pop when played loudly. I called Mesa Boogie about that pop shortly after receiving the amp and got to talk with Randal Smith himself. IIRC, he said the mechanical relay that switches channels is inherently noisy and the technology did not exist for quiet switching.
I seem to have lost the original switch, but recently built a clone from the schematics. Looks just like the original, only a bit smaller.
I am disappointed for what these seem to sell for used. Many are advertised for not that much more than I paid (< $900 shipped) with a few in the $1500 - $1600 range. What do they actually sell for after negotiating? No thanks.
I have had it this long though years of not using it - it is with me for life. A dealer would need to flip it for a profit.
Gorgeous! I was not a fan of the wicker and fancy wood back then. I have grown to really appreciate the look.
