 MISC - Mechanical Filters for Collins 75A4 FS  
Mechanical Filters for Collins 75A4
For Sale:
-
I have a pair of Collins mechanical
filters that were used in a Collins
75A4 receiver. They have been tested,
and both work well. These plug into
the 9 pin socket behind the front panel
of the 75A4. It is quite likely that
they can be used in other receivers as
well.
-
300 Hz filter for narrow CW
-
9000 Hz for AM
-
Each filter is $195. Buy both of them
for $375.
-
Prices do not include shipping from Florida.
-
Thanks. 73,
Ken Simpson, W8EK
