I thought the tubes seemed to be running pretty warm although not red plating . I will do more checking when I have time. Thanks Larry!Check the heater voltages on V1 thru V8(12vac) V9 thru V15 (6Vac) and then V100 thru V102(6vac). Then check B+1(206v) and B+2(160v) on the MPX. 10% variance either way should be ok for the B+. Heater voltages should be no lower than 12.0v or 6.0v. It almost sounds like the heater voltage is too low and it's taking 15 minutes to warm up enough to work correctly. V16 thru V19 are 12vdc.
The plate(Pin3) and screen(Pin4) voltages are a little high, but I'm presuming you are hooked up directly to the wall with a slightly higher voltage than 117vac. Check your heater voltages and adjust the unit to get the heater voltages to 6.3v or 12.6v (depending on what tube you are checking). Once you get the heaters in line, the rest should fall in with no problem.
Steve - can you get any strong FM signals to register 4 on the signal strength meter?

This receiver must of spent its whole life in a multiple heavy smoker home, it still stinks when you put your nose to it, but doesn't put off a stench when using now. I'm surprised it works after so many baths.About the smoke odour: I've got once a small 6AQ5 console pull smelling like an ashtray (and yes, I'm a smoker but always outside of the car/house) and it eventually vanished after a few months, no cleaning. Sure, my nose and taste aren't as sensitive as a non-smoker...
