Default Need Help About Speaker Relay!

Thank you for relying.
What I mean was "can the relay kick on if the OUTPUT TRANSISTORS WERE TAKEN OUT OF THE CIRCUIT BOARD?"

Without the OUTPUT ...C: 33 Volts, Bass: 32 Volts, E: 0 Volts. When I put the OUTPUT back in the circuit board
then the Bass turns to be zero Volts ????

It all depends on how the relay is driven. Different designs drive them in different ways. Most pro amps do a self-check before firing the relay, checking for alsorts of errors. I wouldnt power the amp up without transistors in anyway, it might cause heavy currents through other parts of the circuit, drivers etc

Hi Kev,
Everything is fine , now. Except the relay, it won't kick on.
I found there is ac IC C1237, and I think it is broken.
