This little AM/FM set came to me as a gift from my wife.
It was very dirty and I initially thought is was black bakelite, a
good cleaning revealed it to be dark walnut. To my surprise, the electronics
are in great shape including the filter capcitors and only required
replacing the 12AU6 to bring it to life.
This design was used in various years and trim themes, this model
used a maroon felt behind the brass grill. The original was
in bad shape and I replaced it with standard maroon craft felt that
matched almost perfectly.
This chassis (7H02Z) utilizes a selenium rectifier that should be
replaced for safety and reliability purposes if the set is to be plugged
in full time.
Features include a tone control on the right side of the cabinet.
