[Premium-Rx] Collins Mechanical Filter

[John Hafele]

Greetings all -

I am in search of the following Rockwell Collins mechanical filter :

526-8695-010 or 526-8636-010. Type `PS` 6.0KHz  455KHz C/F.

Very common filter often found in AOR, Palstar, etc. equipment as either
standard or optional equipment. I recently installed the 2.5KHz version of
this filter in one of my Cubic R-2411/U receivers with excellent results and
drastically improved SSB performance. I would like to perform the same task
for AM use, however. The aforementioned 6.0KHz versions appear to be very
elusive and difficult to find. I have tried to locate this particular filter
through numerous sources either new or used but to no avail.

Would someone out there possibly have one of these filters available ?
Kindly respond off group via my email address and any replies will be truly
appreciated. Thanks so much.
