Vintage Synth Repair

Hi Folks:
 I just picked up my Moog Source 
that’s been languishing at American Music Seattle for 8 MONTHS where it went in for battery replacement and calibration with the 
expectation that it was more or less fully functional. After running it through 
some paces I find there are no clock functions for the arpeggiator or sequencer 
and no signs of life from the LFO: no lights from the frequency indicator L.E.D. 
and trying to modulate either the filter or the pitch with the wheel gives me 
only the amount of modulation from the mod wheel with no LFO frequency 
mod added. I see the panel responds to my selecting LFO waveforms and changing frequency but no LFO clock signal seems to be triggered.
 My question is: is there any 
possible mode I might be in that would account for this behavior and is there a 
reset for the Source that might help? Is there a simple ribbon connector that the pinheads who were supposed to be fixing it might've neglected to plug in or that could've come unplugged somehow?
I am officially at the end of my 
rope on getting gear fixed in Seattle. 
   
Thanks,
       Paul

Hi Paul,

The DEMUX on the source is on the analog board, so if it was a bent pin you would have another item or 2 that might not work.

If you don't mind shipping it to MN, I can repair it for you.

Now I do this in my spare time, so it might take a few weeks.

I charge $40.00 per hour plus parts plus shipping.

PM me if you are interested.

Thanks.

Thanks for the kind offer but the Ratbags who were supposed to be fixing it have corrected that problem on their dime.
   Thanks

Hi Paul,

That's good, and so they should.

I stand behind all my work.

Let me know if you need anything; analog synth related :).
