This is a dumb question, but where should I connect the scope? Between
chassis ground on the receiver and line ground on the power strip? None of
the equipment has safety ground pins.

You're going to want to look at the hot and ground legs with the scope,
then. Use a series cap on the hot leg.

A big inductive line filter may fix it.

About what I was thinking. If that winds up being the final diagnosis,
what's a good commercially-available unit? My friend is not a DIY type.

I don't know of any inexpensive ones offhand; the good ones I know of
will all be more expensive than buying a used HHb recorder. A Corcom
filter module might work fine but that would require some DIY work.
