    Paper Shredder Fault

    Sir spike1947 Thankee-thankee-thankee . . . for the feedsacks . . .DEE-lis-cous ! Now, how they define your relevant situation. The presence of the higher voltage supply equates with its being unloaded, if the A44 relay driver transistor was conducting and presenting the relay coil winding as...

    Repairing an old amplifier, working out what is dead

    Since that is a balanced + & - supply, why not place you metering in DC mode 50VDC range . . . unless auto/ranging . . . and then probe the outer ends of the 8.2 K bleeder resistors and see, how close to 0VDC that your reading is being. If not being so, that then gives you a clue as to...
