I really appreciate your doing this, Richard.
I have several home-built (not by me) power supplies for the RAL/RAK here. Each of them
includes a VR-90 for the regulated 90 VDC. I can't remember what the +HV is, but will take a
look asap.
After reading your missives, I will have to check these throughly.
Thanks again,
