[ARC5] BC sets and others.

[Geoff]

If you want a good compact BC set get a post WW2 to about 56 auto radio with 
PP audio; 6 or 12V.

Sensitive with an RF stage, selective enough with the 262kc IF, full range 
tone control.

I have a 49 Plymouth Deluxe model out in the equipment trailer and fed by an 
old 70's regulated 5V 18A mini computer PS bumped to 6.5V by changing the 
reference zener.

A 50 Buick version sits in the garage and a 51 Buick on the auto radio 
repair bench in the basement of the 1830's part of the house.
