Vintage Synth Repair

greetings all,

i am new to this list..

a friend of mine has given me a moog mg-1 to fix..

i was wondering if anyone might happen to have the service manual? 

more specifically it would be a big help if anyone can tell me the 
power supply and fuse ratings..

thanks,

devin

Wasn't the MG-1 the small synth that was sold for Moog in Radio Shack stores about 20 years ago?  I thought I remember seeing all their owner's and service manuals on their web site in Adobe format, though I might be wrong.  It's been a while since I was over on the RS web site.

The power supply options are: 

120V AC / 60HZ (USA)
fuse: 1/8A (125mA) slow blow

240V AC / 50Hz
fuse: 125mA slow blow

Ciao

Hello,
     I have a question that maybe someone could
suggest a solution to.  I have a Crumar T1 organ that
prouces a "crackly" sound when some of the keys are
depressed...I had cleaned the spring contacts a few
months ago with some electrical contact cleaner that I
purchased at Radio Shack, but the problem seems to
have come back somewhat...Any suggestions?

Best,
James

cool, thanks for your help.. thanks to robert as well!

this seems like it will be a pretty cool little synth
if i can get it up and running..
aside from the power issue it is also missing its side
panels.. as well as needing its crappy corroded rca
jacks replaced (being made in co-op with realistic
they decided it needed rca outputs instead of 1/4")
when i got it, it looked as if it had been sleeping in
a swamp.. 
bit of a fixer upper..

thanks again!!

If that MG-1 is missing its side panels, this might be a good time to replace them with some nice walnut or maple sides, stained and varnished.  I've seen a lot of synths with wood sides added.  Seems to make them more attractive.  Not sure if there's room in there to install 1/4 plugs, or worse yet, an XLR connector, but you can try.  I also found instructions on the net for adding MIDI hookups to the MG-1 if you are interested.

I found a web page dedicated to the MG-1.  Seems to be pretty thorough.  You'll find it here:

http://www.kleonard.com/gear/mg1.htm

yeah i was thinking it would be cool to put some nice
wood sides for it.. 

looks like there is plenty of room for the 1/4"
jacks.. its outs are mounted on their own little pcb
which will have to be moved.. but that will probobly
be better than drilling new holes..

i will be pretty happy if i can turn this
dirty,non-working, sideless, halfway disassembled
little synth into a nice looking and well working
piece of gear..

thanks alot for everyone's help! i very much
appriciate it!

i actually have a couple repair projects in the
works.. so i will probobly have some future
questions..

ill keep you posted on the MG1..

peace,

devin
