[ARC5] Looking for info on BC-474 conversions

[Ian Wilson]

Time for my annual time effort to do something with a partially completed
massive
conversion of a BC-474 (inherited from my SK elmer but no idea if it was
his conversion).

The receiver has been converted to use indirectly heated 6.3v tubes (at one
point I thought
that the receiver had been replaced with an AVR-20, but the layout is
consistent with the BC-474
receiver. The transmitter has been rebuilt (incompletely) for something
like a 2E26 or 6146 maybe.

Occasionally I drag this out of the garage and attempt to reverse engineer
the receiver conversion.
There are parts that just don't make sense to me, but a lot of thought and
planning went into this
effort.

Anyway, wondered if anyone recalled seeing a conversion article on this
set, in particular one
which made changes of this magnitude.
