By putting the tubes back in, part 62 no longer burns. It is hard to check the voltage at the cathode resistor since I only had 20-30secs before it burns out. I have double checked the wiring and that part of the circuit is correct per schematic. Only discrepancy I find is the the bakelite cap is 4989-ac rated for .18mf. using one lug on the bakelite, parallel to the 200 ohm resistor. It is superseded to a 4989-odg rated for two .09mf with common ground but using separate lugs on the bakelite. Now what? Hopefully someone can shed some light.
