SOLD
I have available For Sale, a really rare collector's item, a McCoy Crystal Filter in the original box with both the USB and LSB crystals, and the original instruction sheet showing a schematic for 7360 Balanced Modulator using this filter.   This has never been used!!   The filter is centered at 9.000 MC (old school designation) and it has a Bandwidth of 2.7 KC.  The associated crystals are marked 8998.5 and 9001.5 KC.   This filter was the heart of early SSB transmitters home-brew designs in the 1950-1960 era.  NEW PRICE - - NOW $80 (it WAS $100) including shipping to you in the US.
