[Heathkit] HO-10 Monitor Scope transformer

[Peter Markavage]

There was an article in Electric Radio, Nov. 2003, page 28, on the
modification of the HO-10 using, I believe, several off the shelf type
transformers. Don't have the issue handy to look. You might also consider
one of those AC or DC input, HV cube/potted supplies (high voltage/low
current).
