[TenTec] (Inrad-)filter for OMNI VI - some advice needed

[Peter Bertram]

Hello list!

I am going to order filters for an OMNI VI+  but need some advice before doing 
so.

The question is: does the combination of the filters # 753 (9000.6 kHz) and # 
760 (9000.75 kHz) make sense or it is better to order # 759 and # 760 (both 
centered at 9000.75 kHz)? I prefer to listen to a frequency of  about 400 Hz 
but do not want the af-frequency to alter when switching from 400 Hz to 250 
Hz.

Another question is: do the above mentioned filters made by Inrad make a real 
advantage vs. those from TenTec?
