[Hallicrafters] PP-32 Power Supply

[Mike Everette]

The ARR-7 manual is on BAMA for free and it is a
pretty good scan.

Isn't the PP-32 power supply designed to operate from 
400-cycle aircraft power?  If it is the one I am
thinking of, it is designed to run 3 receivers
simultaneously -- 3 rectifiers, 3 filter circuits, but
one common power transformer.

The filter chokes in 400-cycle gear will more than
likely be "lighter" on the iron and inductance than
those in a power supply operating from 60 cycles.  The
filter caps may have somewhat fewer microfarads as
well.  If this is a 400-cycle supply, and you're
building a 60-cycle unit from scratch, you probably
will need a bigger choke.
