Hi Dan,
There are two ways of troubleshooting this set. One is to go through it with a voltmeter and see if all the voltage are as they should be. Some may not be listed in the service info. Like check the voltage at the control grid of the mixer. If it is work properly it should have a few volts - on in. Must check with 10meg input meter no VOM.
The other way is to use a signal generator to test each stage to see what not working.
Just from the sound of it I'll take a guess and say the LO is dieing.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
