In order to offload some of the current from the HV B+ supply here is a suggested separate LV Supply for Clark's 6146 4X4 system.

The Voltage Divider would be energized from the same Keying relay that energizes the HV B+ transformer but on separate contacts.

That way, he can use the 50K 100W resistor as solely the bleed resistor for the 600 Volt supply and not have to worry about multiple taps on it:

Wow, thanks, Phil!  I hadn't expected to see a dedicated thread for this!

I was able to get along with just one tap from the main bleeder (50k/100W) by setting it for the driver plate supply then adding a resistor from there for the screens with a regulator tube.  Seems to work, but disaster struck (see original thread for details).
