Go to ADA Depot : there's tech advice and maybe repair guys who can help.
 
check or switchout the preamp tube(s)...cant remember if theres 2 or 1 in there.

if you could be more descriptive, maybe you'll get more than one answer here? does it fire up. do the lights light up. are you getting signal in, but none out...no signal at all?
 
schematics are nowhere to be found. they are hard to come by.

you can take it to a technician to figure out but if it is a bad chip schematic references will be needed, they are not marked if i recall correctly. I installed a 3TM and cleaned one up before but it has been a few years back.

lesson to be learned - you got it for a steal for a reason :)

ADA Depot is gone. :(

:no: didn't believe you at first, thought to myself that it's not that long when I checked that site but nope :doh: it's not there anymore.

What a pity, it was a great site.
 
I've got a full set of schematics for the MP-1, PM me and I'll get you copies sent.
 
Call A/DA 925 788 4169

They fixed a std-1 for me a couple of years back and were
really cool about fixing obsolete stuff.
 
They are of course hard to get serviced these days. The instrument jack on mine was bad and apparently that particular jack is no longer available. Fortunately the tech I carried it to is the heat and was able to install a jack and make it work.

The mp-1 is a special piece of gear. It is not perfect but it has a unique sound and still has some good tones in it. Despite some seriously good sounding gear out there, it still stands out in my mind, maybe because so many of my personal guitar heroes used one. Hope you are able to get yours working.

I agree. I tried to replace mine numerous times during my rack years ('88-'09) with all the usual suspects (JMP-1, Triaxis, Fish, Triple Giant, Mesa Quad, Groove Tubes Trio, etc) but always came back to the MP-1. When combined with a good tube power amp its hard to beat for classic metal tones.
