[TenTec] Identifying Filter Boards

The Argosy rigs also came stock with a 4-pole SSB filter (9 MHz), just 
as the first Corsairs did.  Replacing the filter with the model 220 
8-pole made a huge improvement in the Argosy, both on CW and SSB.  As 
you can imagine, many did replace them on both the Corsair and Argosy 
rigs so there are probably many floating around loose.  A fellow bought 
mine, removed the crystals and inserted them into his 4-pole.  That was 
above my pay grade, however.
