PSU for valves

Probably Ok for pre-amp valves but not for power amps.

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

Can you recommend an alternative?

One transformer, one bridge rectifier and one or two electros. Get yourself a Variac too. You can run heaters on a 6V battery.

If you cannot manage that, you have no place fiddling with tube circuits.

Hey Pete, Read this one

Even worse overkill than the lab supply.

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

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?

But I'll have the fun (let's hope) of building it myself.

** Building what ?

Did you even read the page at all ?

The author is Australian and known to me, he has long history of being a crank.

So you have a pal.

Thank you for your email. I tried to reply to it, but my reply bounced.
