[TenTec] TenTec Corsair Filters

[KD5NWA@mbayona.com (Ham)]

Hello, I just purchased a Corsair and was wondering in anyone on the list
had filters for that unit for sale. In particular I'm looking for the
following filters

Inrad 750       400 Hz  6.3 MHz
Inrad 758       2.1 KHz 6.3 MHz

Tentec #285   500 Hz  6.3 MHz
Tentec #288   1.8 KHz  6.3 Mhz
Tentec #220    2.4 KHz  9.0 MHz

Also can I substitute a Inrad 756 filter ( 2.1 KHz @ 9 MHz) filter for the
internal one so I can have steeper skirt on the radio's passband?

Please answer to my address only.

Thanks
