[BC] AM Radio Kit

Yep.  Had one of those.  I remember working on it in the kitchen and letting
my bare foot brush against a heat register.

OUCH OUCH......What were they thinking?

I had a Knight Kit AM Broadcaster. 50C5 modulated oscillator, 50C5
modulator, 12AX7 preamp. It had a selenium rectifier and one side of the
AC line was connected to the chassis through the power switch. This was
about 1960.
