Philco 70 If transformer question
#8

I did consider this as always, the 177 vtvm measures the plates at 250 v, my Klein meter reads 269 or so on the plates, so I 'sort of figured' I might in the correct ballpark with the vtvm, but is is 11meg input vs. what they used to measure. I was still a bit taken back at what the 47 bias can do. I still have not decided if I can get a good player out of this radio, if I do, I will strip it down for a full restore from a clean chassis, still not there yet.  I might try changing to 47 filament to DC with a bridge rectifier if the transformer allows it. I am not trying to keep it original, even with the 2.5 volt bulbs and their shortcomings.
