Well crap!!  Was listening to the radio and it was and has been playing fantastic.  All of a sudden there was a bunch of static, and then a station that spread itself from 1300 to 1600 was audible. I was listening to my home transmitter set a 1500. Changing the frequency of the home transmitter I was using brought in different stations.  Interesting!  With the transmitter set at 1470, I had a station that actually transmitted on 1000.  The difference is the IF frequency so I concluded the oscillator died.  Sure enough, the tube was dark.  Put in another 6A8G and part of the dial started to work.  Other parts of the dial were dead. Slowly, dead parts of the dial came to life. After about 10 minutes, the whole dial worked but other bands had problems. The oscillator seems to be a bit temperamental.  This is not good as this is in the tuner assembly which is a b..ch to get at.  Most of the resistors were nicely within spec so they were not changed.  I suspect I have a resistor that has drifted high with use.  Why it all happened at the same time, I'm not sure.  Interestingly, the dark tube will still get warm even though the filament is not lit.  Something in the tube is drawing enough current to generate a bit of heat.  Maybe this damaged something in the circuit.  I'll check voltages once I get the radio out again and on the bench.  I'll let you know what I find!
