HEATHKIT SP-17A / IP-17 HIGH VOLTAGE POWER SUPPLY

Is this a good PS for working on Tube amps?

Thanks

IIRC it is a >150mA supply, maybe lower. Still, there are a lot of PP & SE amps that are in that range.

Tubes like KT88's however would need something in the Fluke/Kepco/Lambda industrial range.

I was looking at this Schematic for a DIY HV PS.

High-voltage bench supply

Nice design and does it all. Could you please explain Industrial range?

How many volts?

Bummer is I have a very nice Lambda Les-EE-02-OV Output 0-18v at a max of 29A. Bought off the bay many years ago for my Brushless motor company. Worked great for that until I started designing motors way out of this power range. 48v @ 150-175A

Industrial means they were for commercial rather than hobby use. The current output was much higher (200-250mA) and they are built like proverbial brick ish-house. The Lambda I have goes up to 500VDC as well. I like the Heathkit and would not mind owning one. For low-current stuff as previously mentioned as well as preamp work, I think it would be great. The bench supply you linked is beautifully done. An ambitious project but it covers all the bases.
