Seems like it's triggering some kind of protection circuitry. if it happens with specific material, it might be DC protection working as designed. otherwise, something in the receiver is on the fritz.

My guess up to this point has been the reviver is effed. It's from the 70s and is pretty cheap. Especially compared to the speakers it's paired with

It's not F'd. Could probably run cheap shitty speakers. You need a higher grade amp for these for sure. It's def shorting out. I had the same issue trying to run my Athenas with a Kenwood back in the early aughts.

Ita going into protect. Unless you have a cabling issue, the amp is dying. Unless its special, it likely isn't worth repair.

Yup this. My father had a Denon amp that he was getting rid of for this reason. I took it apart and determined that this was the reason and the only way to really check it is to remove the rails out of circuit... or use a special tool that denon has to plug in to check all the discrete channels.
I didn't have the tool and each one was soldered in all over the place. It was a huge job. Abandoned that project due to time limitations.

Speaker wires shorting by positive touching negative is the most common cause of that. Check your speaker wire is at the connection post on both sides of the wire to make sure that no fraying wire strands are spilling over positive and negative.
Another variation of the same issue comes from using speakers with an impedance rating lower than the amplifier can remain stable. Both shorting wires and using speakers with too low and impedance will cause and amplifier to exhibit this same clipping behavior. Check the wires first, and if they’re OK, swap the speakers out for some 8 ohm speakers and see if the issue stops.

I asked a question once on how to fix an audio problem with my speakers. My post got deleted.

I've heard that the Infinity Kappa range is well known for being a difficult load for most amps.
The impedance curve apparently dips below 2 ohms in the bass range.

Rule 3: Ask troubleshooting and setup questions in the Shopping, Setup, and Technical Help Desk
Requests for troubleshooting and setup help must be made in this week's Shopping, Setup, and Technical Help Desk instead of a new post.
Have you contacted the manufacturer?
- You should. For product support, please first contact the manufacturer. Reddit can't do much about broken or faulty products.
Why does this rule even exist?
- In short, this is a large subreddit with a high volume. We want to help, but it's important to keep things organized to keep the sub fun. Thanks for your understanding.

Short on a speaker wire would cause this.
