I have FS a like new INRD 108 SSB filter replacement for Collins S-Line
transmitter or receiver. This is a plug-in using a modern Collins mechanical
filter module. It plugs right into the normal filter slots of the S-Line.  I
have used it in both 75S3B and 32S3 and it performs well. I am restoring the
rig to original filter so I don't need this any more. New price is $125, my
asking price is $75 plus postage.

Here's a photo of the filter:

This filter is just a skosh wider in BW than the stock Collins filter, maybe
50-100 Hz wider. This gives a very slightly higher fidelity sound to the
audio (Rx or Tx). Thanks,
