[Hot Rod]

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.
