RE: Moog Source LFO/Clock Troubles

2013-08-29 by <gerryrdahl@...>

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.

GD

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 T
