I have some mechanical filters for the Collins
75A4 receiver available. Of course all work
as they should.

The first is a 300 Hz, narrow CW filter. It
is a Dave Curry Longwave Products filter, made
to plug into the 9 pin socket. $195

The second is also a Dave Curry Longwave Products
filter, but this one is 9.0 KHz for AM. $195

Buy both filters for $375.

Prices do not include shipping from Florida.

Thanks.

73,

Ken, W8EK
