Help, Need circuit for BWD 216a tube power supply


2007-03-18 9:22 am
I was given a BWD brand power supply today,
It has two independent 6v filament supplies, a 250Vdc 50mA variable supply and a 400Vdc 200mA variable supply with variable current limit.

The 400V section is not working.
I've not been able to find a circuit for it.
There isn't even any mention of this particular supply on this forum which I find surprising, so I don't think my chances are good.

If anyone can assist I would really appreciate it.
