good morning,,
thanks for teh reply,,, excuse my typing,, left hand is faster then the right sometimes,,,
yes, all teh tubes light up in teh set,,, i tested them sunday, and the 7A8 was bad, my buddy had a new one, so i am using it,,,,
the set doesn't make any sound,, it will somewhat amplify the dirty volume control, as you turn it,, and i can get static as i probe certain pins with the vom...
i did get a copy of the philco schematic, and my son cleaned it up and made a better copy of it,,, however, it still difficult for me to follow,,, also,, i noticed some discrepancies on it,,,firsrt, the schematic shows two 7C6 tubes,, however, the tube location chart on teh radio shows a 7C7 in the socket next to teh tuning cap...i have tried it with both tubes (no difference in performance),,, and decided that teh schematic was a typo, and teh proper tube layout was on teh radio....

now,, someone was into this set before i got it,, there was half of the 20-20 lytic replaced with a 33mf i believe,, and it was just twisted into teh old wiring!!! so, i figured i'd be in for an interesting ride...
looking forward to your input,,,
regards,
john
