[Collins] Filter

[Dr. Gerald N. Johnson, electrical engineer]

Standard filter for a 75S3B and 32S3. Plug in, fits two transistor
sockets. 455 KHz center frequency 2.1 KHz bandwidth made in the 32nd
week of 1964. Input and output high impedance tunes with about 100 pf.

There's a Collins filter catalog on the CCA page, maybe the CRA page
with no more detail other than dimensions.
