[TenTec] Need parts for Argosy 525D

[Roger Ruszkowski]

Fellows,

I need a filter for my Argosy 525.
I have isolated my problem down to the filter.

I think the easy out is just to replace the module.

I have a 4 pole module part number 48057. NS1 or  MS1 8716

Would any one have a module for sale?

What after market parts could I use?

I looked at some of the web pages and these
were a clear as mud. My Ten Tec PDF file
for the Argosy is not real clear about the
filters band width and center frequency.
This makes picking a replacement some what of
a problem.

Any comments on the filter's bandwidth and center frequency 
would be welcome.


Thank you
