Default Need IF can

OK, been looking high and low for an IF can so I can add a crystal filter to my
cheap receiver. Tired of going through flea market junk looking for an old
tube type junk receiver with a 455 khz input or interstage can. Never found a
single one!

Surely someone has one they can part with. Needs to be the smaller (3/4 in
sq?) with solder tie points. Both windings need to be sorta hi z and should
have two slugs that turn.

Got lots of swapping goodies and a little cash. Which do you need?

How about two older transistor IF cans, secodary-to-secondary. place the
filter in between the low-Z sections and take the output from the primary
of the second can?

The filter will be a single crystal with a phasing cap to adjust the null
frequency. I need two signals 180 degrees out of phase which I will get by
using two capacitors across secondary with the center grounded. This is the
scheme I used years ago and never found another scheme that worked as well for
me.
