Then I found the solderbridge near the hifreq pots and the oscillation was gone. Changed back to LM833 on the hifreq board.

Yes, change both to 20k for a balanced out config.Bonke said:Can somebody please confirm if these are the ones to change to 22kOhm for unity gain?
gyraf said:It is VERY hard to find quad-matching pots accurate enough for this purpose.
The only probable route may be switched resistors on a quad deck switch..

gyraf said:No, not that I'm aware of - it's one of those things that can't be done on a budget.
Though maybe the uraltone switches mentioned somewhere around here are available in 4x23?

I am about to order rotary switches, latching, resistors & PCBs.Graph said:Greeat! Thank you jakob and briomusic!
Thanks!gyraf said:Any 2x15-18V/100mA powersupply will do fine for the Calreq - make that 200mA for a stereo version.
Another question:
I see Purusha is selling cases for a 2ch Calrec with 5 bands. What pcbs and bom is for that one?
