Is the filaments bright or are the plates of the 80 glowing?

If its the filaments then I would check that your getting 5v on the filaments from the power trans. Did the power trans ohm out ok?

If its the plates glowing, then you got a short or something down stream that is pulling major current. Shorted E-cap?


The 83 tube is different not only does the filaments pull more current at 3amps (80 only 2amps) but the 83 is a mercury vapor rectifier.
