Thanks for the suggestions and encouragement!
This time I got no picture on startup, but I did hear a faint whine / squeal, probably from the oscillator circuit (it varied in pitch by turning one of the 3 big wheels slightly). Measured voltages on some easily-accessible pins after one minute, then shut it down after 5 minutes. Here are the readings, using the Philco service manual lug IDs and target voltages (from pages 14 and 15): L11 = +276 (should be +270) L22 = +269 (should be +400) L38 = +262 (should be +260) L40 = +.03 (should be -20) L46 = +.06 (should be +170) |
