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
