Collins mechanical filters for sale
I've got a few of them. First of all, I've got:
450kHz CF @6kHz bandwidth Z=20k These units were used in the Collins 674/U, and later versions of the 651S-1 after the 2nd I.F. was switched. 75 dollars each, plus shipping........new old stock 455kHz USB/LSB pair. I believe that this is the filter set for the Racal 6790 series 100 dollars for the pair, plus shipping 455kHz CF @ 6kHz bandwidth Z= 50 Ohms These were special units for Collins Radio equipment. Good for that single conversion receiver project 75 dollars each, plus shipping Pete |
