You would have to measure the coil resistance and voltage across the coil when activated and then start looking for replacements based on that. If there is a drive fault to the relay then it may not be getting the correct voltage to pull in.
Do you have sound from the speakers ? If you do then the relay is at least closing. If you don't then it might be a power amp problem (dc offset) that is stopping the relay operating and its actually doing its job correctly.

That sounds like it needs proper tests to see whats going on (using a scope).
Are both channels the same ? You can prove if the relay is faulty by shorting it out but if you do then connect the speakers manually after switching on and disconnect them before switching off. Both channels though, well that doesn't really sound like the relay tbh.
It needs a proper tests with a known source

i will careful...having said that, i have a last minute update. I turn it off all!! With no music in play the right channel makes strange noises intermittent, with the Vu Meter right that rises and falls many time, alone, without any input...oh oh, it's better that i do not use anything?
Its very difficult to say what is going on with it at a distance. Given the age of it you might have problems with old electrolytic capacitors having dried out, and problems with dry joints (poor soldering).
The only answer I'm afraid is to test it properly with a scope and signal source to determine what is happening.
The output relay is a very specific part and gives specific faults, but if you are doubtful over it then you have to eliminate it.
