Can someout please give me the pinout for the black Collins "bathtub"
IF filters used in various boaranchor receivers? They have two groups
of three pins on each end of the filter. One is marked with a ground
symbol, but what about the other two?

I've found several excellent web pages that deal with identifying the
filter characteristics from the part number, but I have yet to find
any pinout information. Curious...


Thank you.
