OK, so I was testing my voltages and my power resistors under the power supply of the radio and apparently my 1.5k Ohm 10W WW Resistor just died on me somehow instead of measuring 1.5k Ohms on the multimeter it measured 14 Ohms which is weird because the 5k Ohm "B" Resistor and the 300 Ohm Bias Resistors test fine the 1.5k Ohm Bias resistor is measuring only 14 Ohms, any ideas as to why that would be?

Which I think that might be why I'm not getting any filiment glow or anything out of the Output tubes because the 1.5k Ohm Bias Resistor is part of the output tube filiment wiring.

Thanks for your help.

EDIT: I removed the 1500 Ohm Bias Resistor from the circuit and retested it and it tested fine, apparently I was just reading the resistance wire windings between the two terminal strips where the filiment wires attached to across the bias resistor to ground rather than the bias resistor's actual value.

I think what actually is wrong is that the output tubes are just bad and I think they failed because the output tubes weren't replaced as a matched pair when one of the tubes failed at one point in time (which apparently according to my Rider's Tube Substitution Guidebook with the 71A tube when you go to replace the tubes when they are in a push-pull configuration they need to be replaced as a matched set or they could fail prematurely due to biasing issues between the two tubes, which I think is precisely what happened in my case).
