OK

Thank you for the question. I initially tried it with nothing connected, but added speakers to see if there were any audible signal, or if it would act differently, but there was no change. I didn't add anything else because I didn't want to risk damaging something else. Thanks again.

That's a good idea, I'll look through the photos, I'm sure I'll find some reference numbers. I'll post what I find. Thanks

I have downloaded the Owner's and Technichian's Manuals from here, and they are helpful, but I'm either not seeing the voltages, or they aren't listed. Any help is appreciated.

I've been working on my new-to-me HR-772 receiver, and I could use some help. I picked up the receiver from FB marketplace for $120, which I think is a steal, but it has a couple of problems. I noticed that when I would turn up the volume the sound would get "thin", also, that the remote control would not work. I looked at the main caps and saw that they were bulging a bit, so I replaced them along with all of the other caps on the main board with hi quality caps. Here's where the problem began. Now when I turn it on, it goes in to protection mode after about 5 seconds. In that time, I can verify that the remote control works, but now the entire system goes into standby/protection mode. Does anyone know the proper voltages that should be expected out of each of the main transformer leeds, and after each power supply filter caps? I think I might be getting too much voltage out of the transformer, but it may be something I did. If anyone has any advice or information they can share about their experience, I'd be very grateful. Thanks
