Power Supply For Tube Circuit Development

[ZeusMC]

Are there any alternatives to the Heathkit Ip-17 regulated high voltage dc power supply?
Thanks.

Look at ham radio gear for alternatives if you can't find a stand alone supply in audio?

OK, thanks for the tip.

Hickok Teaching Systems (the same Hickok that made tube testers) produced at least two high quality variable supplies, models 5055 and 5056. I believe they're identical except the small 2.5A variac in the 5055 was deleted in the 5056. These were made specifically to power vacuum tube and SS equipment. The 5055 that I use has the following outputs:

6.3 VAC, 3.5A
12.6 VAC CT, 3.5A
0 to 40 VDC, 1A
0 to 400 VDC, 150 mA
0 to -100 VDC, 2 mA

Good luck in your search!

OK thanks I have read about their tube testers but didn't know about power supplies, thanks again:)

Do you have any documentation for the 5055?

Do you have any documentation for the 5055?

Yes, I have a schematic somewhere. The circuitry is somewhat unorthodox, but not overly difficult to work on. There are no tubes in this supply, it's all solid state.

Another option is the B&K Precision 1602.

They seem to be pretty rare though. I had to check eBay every couple of days for over a year before I finally found one in decommissioned status and unknown functionality, but it works great.

The instruction manual has a 1980 date on it, so they appear to have been made right at the tail end of the tube era.
