Minimoog Contour ADS problems

[dancelwerk]

Recently I repair one minimoog(below 10175), with vco2 dead, but now when I connect again after assembly, I can hear that the contour filter ads doesn't work, before it was working. Is very strange.

Loudness contour is ok, except if you open decay in the middle position or away, you can get a release of minutes long, I can't compare with other minimoogs, but I think is it not normal.

Should I be change all the caps on this contour board,? or it could be any transistor of the filter contour?

I am a little lost where I should be to begin.

Other thing is that with all volumes and filter knobs at 0, less the output volume knob of course, you can hear all time the three oscillators at very, very low volume, even if cuttof frequency is 0, perhaps is related with the vcf contour fail.

Thanks in advance.

Fernando.

The board connectors tend to get flaky with age. Try applying pressure from the back toward the panel right above the connector and see it if works.
