Hi All,

I've had 2 of these 573's for about 6 years now. They have worked well and I've never had an issue. About a week ago one of them stopped giving any output signal. I say "output" because I can clearly see that input is coming in because the LED is flashing and responding to the input gain. Today my second 573 has done exactly the same: no output, input LED flashes and responds to input gain. I've taken all the modules out of my 500 rack and verified that my working preamps work in all slots and the 2 573's are not working in any of the slots. If anyone might know what the issue could possibly be I'd be grateful for any insight.

Cheers,
DW

Can you check the DC voltages?

Thanks for this but I'm not in the position at the moment to do this. I don't have an 500 insert extension so I can't get to the test points even if I empty my 500 rack. I guess I'll just have to send them to repair.

Did you get this resolved? What was the issue?
