Quiescent current Solvsuper 12
I cannot find any info how much the quiescent current should be and what points are used to set it up. Thanks for help !
I happened upon the following information on a Facebook group for Tandberg repair. My translation below is accurate, but I give no guarantees that the information is correct:
“The SS12 circuit diagram states a 0.015V voltage drop across R837-8 This gives a quiescent current of 32mA. Hence, adjust the quiescent current until the voltage across these resistors is 15 mV.”
@MrTron thanks a lot , I set up 12mV as I recal so I was close 🙂
Hi....the 470k pot ought to change the mid point voltage, which as indicated by the schematic you posted ought to be 13 volts at the intersection of R532 and C519.
The 1k pot ought to change the peaceful current for the yield pair whatever that current should be, there's no sign of that in the schematic you've posted, as an estimate I would say somewhere near 8mA without any cited figure.
OK, thanks !
