Thanks, orange! :slight_smile:

In the clone schematics, some opamps miss the +15v/-15v supply, but it is clear that they need them just as the others

Hi Peter,

I see no fault in the opamp part of the schematics; if you look at the pin numbering the schematic uses dual opamp ICs (U1a and U1b for example are 1 IC) and these have only 2 supply pins for both the opamps.

Cheers, Alex.

Hi Alex,

thanks a lot for the clarification! :slight_smile:

It all makes perfect sense now, I treated the TL072 dual-op-amps, which were correctly marked e.g. as U5:A and U5:B in the schem as two single-op-amps and was wondering why one of the pair was not connected to power…

Hehe. Great, the schematics are all perfect then! :slight_smile:

Many greets,

Peter
