I did replace the vid detector recently. After the recap of the set I had dead audio and video. Replacing the diode got me to where I'm currently stuck at. I'll check polarity tomorrow and flip it around regardless.
Yes I did get quite worked up over voltages. They just weren't making sense what was happening. And the higher negative voltage on the IF grids has me bugged.
Browsing on ebay for a VTVM.. Wife won't approve I'm sure.. So many to choose from, and not all are come with leads or that are guaranteed.
Before leaving my parents house I went over every single resistor in the AGC circuit. The circuit was wired correct and resistors were in spec. The 6T8 pin 6(AGC diode plate) the resistance measurement didn't add up. Should have been 1.5 meg but was reading low. I disconnected the mica cap(150MMF) from the AGC diode plate to ground and the the value bumped up close enough to 1.5megs. I'll have to find replacement somewhere. Not sure what its purpose is.
Definitely getting flustered working on this set. Not sure if Philco's quality dropped by 54 or what... This was a very basic 21inch set.
