I need a ckt for a Q Multiplier, possibly by Heathkit or others. A ckt from a Ham or commercial radio receiver might be useful!
Schematics for the QF-1 are pretty easy to find.

There are tons of schematics for various receivers. Might want to be a little more specifics about what you are looking for and why. That might lead to some specific directions. Otherwise just look here...
