Time to buy one of these pcb's since I am sick of running through my console as a glorified output select and
level control. With horrible stereo tracking

Thanks John, yes, at first I didn't checked the schemo, just replaced all the caps at the board. Now, when I saw the sch. I figure out the "missing" caps. I will check ASAP with scope, but adding two caps from 6 and 9 to GND cant make it worse… maybe I can go with 15nf ?JohnRoberts said:Huh... I don't see any caps on the encoder...
Maybe put a scope probe on the two lines going into the micro (pins 6 and 9) and look for clean edges as you rotate the encoder.

You said you replaced the encoder, so it "should" be working correctly.
Caps might help but doesn't explain why it worked perfectly for years without them.
Clear Yes, I will experiment a bit. Still don't understand how it's possible that it worked withouth caps smoothly . Maybe I have to change few encoders to find accurate one.JohnRoberts said:The clicks are just mechanical so do not affect the micro other than tell you it should have registered.
Before it was getting too many counts,
Now not enough.
Maybe use smaller caps.

I thought you replaced the encoder... is it a new one? If not, dirty intermittent switch contacts can cause issues.Moby said:Clear Yes, I will experiment a bit.
