Question about Audio & Video Receivers
HOWDY, NOW YOU COULD TRY THIS ONE: POWER THE RECEIVER UP , THEN PUSH&HOLD !THE VIDEO 1 BUTTON, THEN TURN THE PIECE IN THE OFF (STANDBY MODE ) ,IT WILL SAY "CLEAR SO IT SHOULD BE BACK TO IT,S ORIGINAL FACTORY SPECIFICATION,S. SUCCES ! AMSTERDAMCOWBOY-HOLLAND-NOW FLORIDA! 4-EVER

The transistors you need are 2SD2560 and 2SB1647. (either you miss-read the D for a B or it was a typo) You can get them at: www.mcmelectronic.com
2S is a prefix on all Japanese transistors.
The 010 is a date code
Also check for open resistors from the base of those transistors and the dual emitter resistor (large white three leg resistor .22ohm)

Though any transistor(s) might well have gone and the capacitor could be changed, I see no reason to change any resistor unless it's burnt up or giving an incorrect resistance reading. A multi-meter will tell you if a resistor is working or not, if it's not dead or weak it won't make a lot of difference to the circuit, but replacing it will simply cost you more money!

There are independent relays for the speaker A and B switching.Best place to start would be from the relay. When you select A do you hear a click, if not relay is not switching. The circuit involved is a small transistor , a low value resistor ( could be the culprit ) and a shunt diode.

Testimonial: "Thanks. I knew there had to be something like this. I'll follow your advice."
Honestly, if you are talking about the speaker protection relay, the relay and associated circuits rarely go bad but instead respond to problems elsewhere in the amp. Anything from defective speakers, bad spkr. wiring to output transistors will cause this protection relay to not energize thus protecting the output stages and speakers.
