Wondering if anyone has experienced this. I have Pro-Ject turntable hooked into the analog input and after a hour or so of loud play the right channel stops. I think something is getting to hot because if I let it cool for a few moments it starts working again. Even if I switch inputs to radio or disk still the right channel is out.

I have the 975 hooked into the 7175, and I'm not sure if the issue is the pre or amp. Any ideas?
