Collins Original 75S-3B and 75S-3C , F-455-FA-21 Filter 2.1 KC P/N 526-9427-00 Tested & Guaranteed

 This  2.1 KC filter is the standard SSB Filter factory supplied for the 75S-3, 75S-3C and a Rockwell Collins KWM-2A. (Only the Rockwell Collins KWM-2As use the F-455-F-21 Plug in Filter)

 This Original Filter, is in excellent condition.

 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.
