IN 1970, there was a two-part article by Fred Brown about updating an
HRO receiver. He replaced the full size tubes with more modern
equivalents, did some other changes, and ran it at a lower voltage than
originally. He gave all kinds of reasons for the lower plate voltage,
and mentioned that the Collins S-line receiver used lower plate voltage.

I recall that at the HAMfest at Birmingham (AL) several years ago
(possibly as many as 15) some chap had a BC-348 that he had converted to
solid state. All of the tubes had been replaced by transistors - and it
worked pretty well - at least there in the Jefferson Convention Center.

I've thought about trying the same with one of the arc5 receivers - just
never got around to it. Dave Stinson would probably be one to ask about
such a project - Dave- got your ears on?

best regards...
