Hi Ron and all,
I can't seem to find the schematics that were on the original philcoradio site, and I need one for my model 90, with the single 47 output tube. Could someone direct me to the location on the Phorum where I can find the schematic? They are the best I've seen. I need to know the values of the bleeder resistor 58, as well as the DC resistance of the field and output transformer primary, since my speaker's transformer and field are both open (along with the broken cone). Could someone please point me to the steps I need to obtain the schematic for the 90? Thanks so much, all...
