Collins Original 75A-4, F-455-J-15 Narrow Filter 1.5 KC P/N 526-0155-00 Tested & Guaranteed

Collins 75A-4, F-455-J-15 Narrow Filter 1.5 KC P/N 526-0155-00 Tested & Guaranteed.

 This  1.5 KC filter ican be used on SSB as a narrow filter, or on CW as a wide filter. It can also be used for RTTY, but that mode is rarely used these days.

 This Original Filter, is in excellent condition.

 All original Collins 75A-4 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 75A-4 filters out there for sale and many have degraded performance or do not work at all.

This filter comes with a satisfaction guarantee.

 I have several of this bandwidth filter and they are all in similar appearance. The nomenclature stamping may be different that the one pictured.

 I also sell the Dave Curry NEW Collins mechanical filters in another listing.

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