Philco 514 Questions
#8

So here's a progress report. All the coils and transformers have continuity. Tested 2(20 & 37, 70K) resistors they are way off, replaced them. Re-stuffed the cap. in #27 which is the output to the speaker. Discovered the wipers on the hum controls are not making contact. Removed the wipers(they are open to the fresh air), cleaned, adjusted and re-installed. Now tests good. Tried cleaning the power switch, worked for a few minutes then became flaky. Cut that sucker out and put another part on the order list. Slooooowly applied power to the PT with no tubes and measured the secondaries at 120 VAC on the pri. YES!! all are good without load. Replaced the four .1 mfd caps in the RF and speaker circuit(7,12,17 & 39). Started cleaning the chassis and cabinet. Waiting for delivery of parts for the messy power supply filter cap. box which was removed from the chassis.

That's it for now, Rod.
