Restored Philco 46-420 code 121 has slight low pitch hum.
#14

I don't want to beat a dead horse but in post you said:

"Try connecting a 20 or 30mfd 160v cap, the + side to pin 4 of the 50L6 and the - to B-."

There was never an electrolytic on pin 4 of 50L6. There was (and still is) an electrolytic on pin 4 of 35Z5 so I'm going to assume that's what you meant.

In a later post you said "I meant 50L6 not 35Z5" so that was confusing me.

I'll go ahead and solder in another 20 mfd across the pin 4 of 35Z5 and test it.

Thanks.
