Is this usual in Philco sets?
#4

Hi and Welcome!
Always like having a look at the UK models vs are US sets.
Typically the US sets wouldn't have B- connected directly to the chassis it would be floating and have a cap between the chassis to B-. Your set is the other way around.
I would remove the earth wire as it does make for the possibility of a shock hazard from ac leakage thru the capacitor depending on which way the plug is connected to the mains. With that being said using the neutral as the rf ground is a bit noisier than using a separate earth ground (separate from the mains). Now days the mains are full up with all kinds of rf trash from switcher power supplies and microprocessor controlled devises. The further you can get the rf ground away from the mains the better/quieter it will play.
In most cases the US models are pretty different from the UK built sets. I think the US set would be this one the 48-464. Outside looks the same but under the hood it's way different.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
