This certainly should be usable for most battery type sets, though I have an ACE (Harry F. Alter Co) battery console which allows multiple tube choices for the output, so I decided to try a 71A which requires -40V for bias at 180V plate. Then I tried a 112A which needed an odd -11.5V @ 180V Ep. If I didn't already have a Heathkit IP-17 HVPS and had one of these instead, I'd probably want to modify the C circuit for wider range and variable voltage rather than the usual voltage steps.
we NEED the schematic!!!! How can we troubleshoot when we have a problem. There is nothing special about the design. Typical series regulation of all voltages. Please give us the schematic. Tracing out the circuits is a waste of my time!

I got an old Philco radio from my grandpa and I know nothing about creating circuit boards. Is there a place I can buy a pre-built battery eliminator?
Does the provided parts list have part numbers (eg Mouser) to make it easy to source the required components?
Who you give credit for the design?
Your bench is too clean. Affects your credibility. ;-)
You should see what's just out of the frame, a lesson in entropy.
