I thought I'd experiment with a few valve circuits (just for fun). So
I'll need an H.T. power supply and I'm looking at this: https://www.timstar.co.uk/el120300-high-tension-ht-power-supply.html
It supplies up to 300V at 60mA. My question is, is 60mA sufficient?

** That is clearly a regulated lab supply for experiments in physics.
Major overkill for playing about with tube circuits.
Expensive too.

Even worse overkill than the lab supply.

You're such a bugger when you criticize Phil :-)

Even worse overkill than the lab supply.But I'll have the fun (let's hope) of building it myself.

Thank you. That's really helpful. Looking at the first circuit
diagram, any thoughts about the value of the pi filter choke? Also,
looking at the second circuit diagram, the swinging choke is marked 20H,
but the smoothing choke has no value given. Any thought about that?
