[ARC5] WWII Transceivers

[Ian Wilson]

I have a couple of tunable IF strips that I haven't ever been able to ID.
They are
presumably for a transmitter since the output stage is a neutralized 6CL6.
There
are one or two 6BA6 stages and a 12AT7 mixer on the input. Collins
manufacture
apparently. There is a rod mechanism that moves tuning elements in the IFT
coils.
If I recall correctly these are in the low MHz region (the ARC-2 IF
reminded me of
these). Anyone?
