Wish you were here album.

Well, here’s what I have experienced. My MXR had a perfectly working thermal protection system. I think those receivers are an 8 ohm unit and the Cerwin Vegas that I paired with them were 4 to 8 ohms. That receiver was abused in many many parties to the point where it would get so hot it would shutdown. I let it cool down for a few minutes and it would come back on. Then I bought a FAN!!! I wouldn’t buy anything as far as amps or receivers that didn’t have a protection mechanism in it. When I am pushing my amps I always have a fan on it. So maybe the amp is letting too much current flow with lower impedance speakers. I would be more worried about it if I was a person like I used to be. Now I’m not listening to music at the levels I used to so this is not something I worry about anymore and on top of that I can just repair what I burn up. 🤣🤣🤣 But yeh, Impedance is AC resistance. I can’t hear anything on DC current.

Welcome to the site. The MXR 150 was my first purchase and my only carver piece for more than 30 years. I loved it. Enjoy the power.

I have seen damage very similar in many other Carver amps typically in TFM's. They get very hot and burn boards. But that one looks like it was cooked nicely.

Welcome to the site.

If the relays are not clicking, more than likely the unit is in protection mode and they won't click on. Did you say that you speakers won't work on another backup receiver? If that's the case I wouldn't think it would be the transformer this early in the diagnostic stage. If the speakers won't work then it was probably them that did something to the protection circuit in the receiver. Any fuses inside of the unit hiding under stuff that might be blown?

VR452 is a 150k pot but I believe I used a 200k pot from another model before. You can still find pots that will work. Sometimes it just takes some digging.

Welcome to the site. Greg @ Nelionaudio might have the part you need. Send him a message through his service email. He now has the receiver collection that I had.

Great to hear.

Welcome. Could be a couple things. Relays, balance knob or the switches on the input board that the cables go to from the source and dubbing flat knobs. You can spray those switches as well as the balance knob with deoxit and work them to see if it helps. You can get to them by removing the bottom panel.
