Was there any info found for this tester
Some one must have a good copy of this.
Thanks

looks like radiomuseum has a schematic for download although it may only be the actual schematic not the other pages. It might be more readable. You have to fill in a bit of info to get the download but I've done it before, not hard.

Thanks, I have those already.
Thought there might be something better out there.
A little less fussy

Moe,
I see you discovered the "information" posted at https://antiqueradios.com/forums//viewto...p?t=309831. Non too clear in my estimation.
It has a variac [as you must know]. But with output voltages from 90AC to 140. Any idea why it wasn't designed to start at 0 volts?? Or if it can be modified to start at 0 volts.

Sorry, Have not spent much time on this unit. Just too limited of info to continue.
Thanks for the interest.
