You seem to be asking for two different things.

Do you want to homebrew a radio to receive AM, and are looking for some
candidate filters?

Or do you specifically want to build a Heathkit tube rig or use the
Heathkit SSB and CW filters in a rig, and you want an AM filter to match?

If it's the former, then find out who's selling replacement filters (the
name "Fox Tango" floats up to my consciousness) and see what they have.

If it's the latter -- well, the same place may have what you want, or you
may be out of luck (did the Heath rigs _have_ an AM selection? Mine
certainly didn't), or you may have to mix to some other frequency (i.e.
455kHz), filter, and mix back. Note that my SB-201 didn't have an AM
detector, either, so it may be more than just a filter that you need.
