Thank you Brach for your help!
I already replied to your last message about 12 hours ago, but the message vanished again. There’s something about your SPAM filter making this a little tedious for me. One idea: I used the omega symbol for resistance values. This might be interpreted as malicious content. Maybe you can see if that’s the issue with the forum here?
In short:
The jumpers are not the issue, measurements are taken with jumpers unsoldered and checked fo no continuity. I redid the measurements: 5k on Low, 21k on High at the lowest setting of the trim pot (full clockwise until clicking through). Everything else was set as described in the manual page 46ff, LFO not pulsating.
I’ll wait on your input before attempting anything else.
