Are those PSU voltages with the PSU under load or not? It really is a little too high for CMOS. Adjust the PSU if you can. The 0.74 drop is fine.
The pots are wired between +VE and 0V, with the wipers going to the resistors, so yes, they are for sending fixed voltages in parallel with the CV inputs.On Tue, Apr 19, 2016 at 1:49 AM, philippe@... [cgs_synth] <cgs_synth@yahoogroups.com> wrote:I see, thanks Ken
I found the diode just after the +15V was dead, so that's why I had a continuity and the same voltage on the C padbtw, my PSU delivers +15,48V on the positive rail and -15,54V on the negative. As the +14,4V only relies on the diode resistance apparently, I have +15,19 instead of +14,4 (and -0.74V instead of -0.6V). Would that be a problem for the circuit or the chips ?Another question I had about the WRS: I don't find anything in the docs or the schematic aboutt how should I wire the pots for the inputs. Are they supposed to be simple attenuators, or sending fixed voltages in parallel with the inputs (as there a 8 of those) ?ThanksPhilippe
