All the resistors are within 20% and most within 10%. I have gone through the radio and replaced all out of tolerance resistors. The bias on the output tube is correct. I did measure the output of the variac (103 volts AC with the dial set at 100). All tubes have also been tested and are good. The radio works very well.
One thing I did not do, and will do, is measure the high voltage INPUT to the rectifier and compare THAT with the voltage table in Riders. I'll post the results.
No way would I plug the radio directly into 123 volts. I did try it through my bucking transformer (110 volts), but the B+ is still WAY to high (325 volts vs. 275 listed in the voltage table in Riders). I suppose the voltages in Riders could simply be WRONG. But even if so, the B+ greatly exceeds the tube manual maximum screen voltage even at 110 volts in, let alone 119 volts (the basis of the table).
