Tube Bench Supply
 

I need to buy or build a bench power supply to test & design various tube
equipment (audio & ham). I would like it to be something like a Heathkit
HP-23 with voltage & current meters. The major problem with the supplies
I've come across such as the HP-23, is that the B+ current is appx. 100ma.
The bias & filament supplies are OK, but at times I need around 400ma for
the B+ out. Is there such a PS available, perhaps with tube regulation &
rectification or do I need to build from scratch? Any answers will be most
appreciated.

Cordially,
