re: SU-V85A

I have a problem with the resistor at R477 on the schematic for the Voltage control Amp. circuit. it says it is a 22 Ohm resistor but no clue as to weather it is a 1/4 watt or a 1/2 watt. I have tried 1/4 watt and it fried and popped the cap at C463Anyone have any idea?

re: SU-V85A

Try replacing R477 again, and also replace C463. I suspect the cap was leaky and it would have fried the resistor. Let me know how you get on.

re: SU-V85A

can I play two sets of speakers simultaneously by pressing the main and remote buttons to on position?

re: SU-V85A

Yes, two 8 ohm sets or one 4 ohm set

re: SU-V85A

From the schematic I'd say yes, although as it places the speakers in parallel you'd need to use two sets of speakers with 8 ohm or more impedance.
