Re: [TenTec] Filter Identification Help

[Bwana Bob <wb2vuf@verizon.net>]

I have the 4-pole filter that came out of my Corsair when I replaced it 
with a 8-pole one.  It is 9 MHz, has 4 crystals and 5 caps.  The PC 
board is marked "6840" (had to use a magnifying glass to read the 6). 
One of the crystals is stamped "8235", which may really be a lot code or 
date code.
            73,
