Moog Prodigy Advice

Hi all.
I'm looking for some advice. I have a Moog Prodigy 336A. Cosmetically really nice, only missing one slider, no other real cosmetic issues.
But... I turned it on one day and no sound! :( (It worked fine one day, stayed in tune, played like a dream, then...nothing. Oh the pains of owning a vintage analog.)
Anyway, I have a Little Phatty that I love, and live in an synth tech impoverished area, so there's not much incentive to fix it.
Anyone have a notion of a fair price to ask for a Prodigy that powers up but makes no sound?

If you're not scared, you can crack it open and check a few test points. My guess is an op amp in the VCA or VCF.
Where are you located?

Could be one of many things, but start by checking the fuse and power supply. Is the 'POWER ON' LED by the pitch/mod wheels lit?

If the power is ok, check the jack connections and cable between the Prodigy and whatever you're connecting it to (mixer/amp etc.).

Check the obvious things like panel pot settings to make sure an audible sound *should* be produced - easy to overlook sometimes.

If all the above fails, are you getting any kind of sound at all? A hiss, a hum, anything?

I love these 'one and one' posters.

We offer suggestions and advice but never hear anything back. :roll:

Too many of them want their analog synth fixed for free over the internet. I pretty much stopped responding to them - my time is not free, I have too many other things I want to do, and it is way too much work to coach novices in the skill of analog electronic repair.

I would get a lot of those through PMs too, and one idiot was trying to shame me into fixing his analog synth for free. So I disabled PMs - no more.

I completely understand your position on that MC. I have it 'real life' too not just on the net. "Oh! I know a guy called Steve who can fix up your Moog/Korg/Roland Whatever the damn thing is" - even though the 'damn thing' has been sitting in a damp garage for 5+ years.

Haha... sometimes those suckers can be of serious value. I scored my Rev 1 Prodigy for $15 because the owner thought it was dead. Filter was closed and he didn't understand the instrument. Do I feel guilty? Slightly... but if you don't know what you've got, you don't really deserve it... Just my two cents. It is in loving hands now and has been cleaned and restored to near-mint condition. 8)

No need to feel guilty at all. You saved an important instrument (historically speaking) from the garbage dump. Well done on the restoration job. If it wasn't for people like you then so much of synth history would have been consigned to the rubbish bin of eternity.
