Briggs PS-B valve Regulated HT power supply

[Electric dabbler]

Hi ,

Has anyone got a circuit for one of these power supplies?.

I need to know what the main output valve/tube is - its an octal base device
and unfortunately its missing from the supply I have. The other valves are
an EF86 pentode and a GD150M voltage stabiliser.

Failing that any suggestions of what I might use - this thing is a variable
0-300V supply with 60mA output capability.

Any suggestions gratefully received

Philip

No its not a variac its an active circuit with two valves and a gas
discharge voltage stabiliser. I imagine the output valve is something like
an EL34 but will need to check the pin configuration..
