I noticed one of the 811's filament was open so I inserted a replacement. Apparently the replacement plate was shorted to ground and blew one of the 8 amp in line fuses. So I had to reopen the top cover to remove the bad tube but failed to properly tighten down the cover and the shorting switch was grounded. When I turn on the power smoke poured from the power supply section. An inspection showed two 10 ohms in parallel resistors blew apart.
Now I'm trying to locate replacement 10 ohm 2 watt carbon resistors. I will report next time after I replace the resistors.
