Oh yeah, FC not VC. Good catch. That's what I meant. I do understand the difference. And thanks for instructing me on how to check the voltage. I wasn't sure about that. I'll check those 6L6 voltages too and take notes on everything.
Any ideas about why the treble control diminishes the volume? That symptom is why I was going to dig into the IF expander. Very possible that I have more than one problem. But at least I have a working radio and somewhere to start.
I have yet to bench test anything powered up because I have to clear the table in my garage. Need lots of room to spread everything out. That'll be this weekend. I haven't removed speakers from the cabinet yet. I do know about the diffuser cone under the woofer. I've been researching this and other sites for quite some time.
