Restored Philco 46-420 code 121 has slight low pitch hum.
#15

>pin 4 of 35Z5 so I'm going to assume that's what you meant.

It wasn't what I meant. On the 35Z5 it has no internal connection on pin 4 and the schematic doesn't show any connection there. With that being said I have no idea what is connected there ( it's used as a tie point).

>There was never an electrolytic on pin 4 of 50L6.

This is true. But there is a wire that connects to the second filter that IS connected there (pin4 of the 50L6). I chose that point as it was easier to describe than trying to describe the different between where the two + sides of the filter are connected.
