Back to my Philco 46-250. So we got the tube thing figured out. So I have two AC wires coming into this set. Black and white. White being my neutral/return, does it connect to the rectifier tube through the dial light or does it go through the on/off switch? Or does it even matter? Also this set had a #44 6.3 volt dial light bulb in it when I got it. Bulb was fried. Does the dial light in this set have 120AC going through it? Looks like it by the schematic. What type of bulb goes in this set? Does something happen in the rectifier that drops this voltage?
Thanks,
Johnny

Have a look at the print for a 46-200 this is how your power supply is wired with a 6.3 volt pilot lamp, and 35Y4 rectifier, three filters,

:Thanks Warren,
I guess the problem I'm having is two different Philco engineers using their symbols in different ways or maybe my 46-250 schematic has a typo on it.

On the 46-200 you referenced, on the left side of the schematic there are two ground symbols. One, the pitchfork is noted as B- and the upside-down xmas tree is noted as the chassis ground. If you look at the 46-250 schematic these symbols are reversed. Upside-down xmas tree being noted as circuit ground or B- and the pitchfork being noted as the chassis ground. So which is right?

The rake or pitchfork always is chassis ground. The upside down xmas tree is circuit ground. Where your filter capacitors black ( negative ) lead is connected, that is your circuit ground, or B- .. The white AC cord lead (wide pin) should be the switched side, and goes to circuit ground, not chassis ground ..

:Thanks Warren. So I do have my set wired correctly.

The common side was switched in these sets to reduce hum pickup. This leaves ac on the circuit common even with the switch off since there is a path through the filaments. It is safer to rework these sets so that the circuit common is permanently connected to the neutral side and switch the hot lead instead.

Of course how much safer depends on all the outlets being correct(hot-black-narrow slot, neutral-white-wide slot, round-safety ground-bare), so that needs to be checked too. Or you can leave it as is and remember that folks were supposed to be smart enough not to use these sets in the bathtub to start with.

Yes, this is very true .. If you would like to make a modification to deal with this problem, here is a good link on what to do about it .. It's for a Hallicrafters radio, but same thing for just about any AC/DC set.
