Yamaha CA-800 Channel Out.

This is not making any since..:idea: I have a CA-800 parts unit with and unmolested PS board I think.
 
Everything works as it should just that relay clicks immediately and there is a thump in both speakers.

and a little hum from the right amp and even less on the left amp.

I can't remember for sure now if the old relay clicked immediately, and I tossed it!

Would the relay from my parts unit 620 be the same?

If you hear and instant click. Its not the relay. Its the control voltage getting there to soon.The slight delay is to allow your regulated power supply to stabilize first.
 
TR709 replacement is ecb, check that it matches the icon on the circuit board. Flat face should be facing 2 large caps
EDIT: OK, you've got a different version of the board, also icon may not be correct for that board.

Looking at the icon and comparing it to the t existing c458's it may be in incorrectly
