Re: Making a safe 1KV source!

I think Jim's bench is still at the Computer History Museum in Mountain View (Ca). Never been, even though it's only a few minutes away.

REMEMBERING JIM WILLIAMS..... WE MISS HIM

WHERE IS HIS "BENCH' NOW ??

...BOB...

You can buy an electrophoresis supply for $50, some
will do 500V, some 2,000.
High voltage supplies -- don't try this with an ordinary
transformer as the insulation will break down -- for most
tube equipment over 600V and you are past the margin of
safe

Some resistors have a DC resistance coefficient -- best off
with resistors made for the purpose or place several in
series.

A must read by the late Jim Williams:
