Rockwell Collins Original 75S-3B and 75S-3C , F-455-FA-40 AM Filter 4.0 KC P/N 526-9497-000 Tested & Guaranteed

 This  4.0 KC filter is an AM filter for the 75S-3, 75S-3C, and Hammarlund HQ-215

 This Original Filter, is in excellent condition.

 Rockwell Collins Filters are the latest version made and there for the newest filters.

 All original Collins  filters I have listed, have been tested, measured, and are within the original specifications, and any filters that did not measure up were disposed of.

 There are many used filters out there for sale and many have degraded performance or do not work at all.

This filter comes with a satisfaction guarantee.

 I also sell the Dave Curry NEW Collins mechanical filters for the 75A-4 in another listing.

 They come in either .300 KC for CW and 6 KC for AM. All other bandwidths are no longer available.
