Hi,
I bought an old Polysix that have been standing in a cellar for a longtime, and it was non working, and I suspected the leaking battery of course.
And that was one of the problem, the leaking battery.
So I replaced the battery and cleaned up everything and I repaired all the broken leads I could find on the circuit board.
And I have been checking every lead around the Processor and IC 30 and IC 31 and they all seems fine now.
And all the patchbanks works as they should now after my repair.
So now I get sound out from the Polysix and most of the functions seem to work as they should, but there is one big problem and that is the envelope generator controls.
When I turn the ADSR buttons it sounds like they controlling the filter instead of the envelope, they dont do any changes of the envelope at all.
So my question is: Can this malfunction still due to broken leads that I dont have found on KLM-367 or is it more likely that the problem is on another board now?
