[TenTec] Need parts for Argosy 525D

[Al Gulseth]

Roger,

The 48057 is the stock 4 pole 2.4 KHz filter used in the  9 MHz IF of the 
Argosy and Corsair (560, not the 561 Corsair II.) The model 220 (or 48058) is 
the 8 pole version and is a "drop-in" replacement for the 4 pole with steeper 
skirts and better performance.

Maybe you've already seen this, but here's a chart of the various filters and 
part numbers:
