[Collins] Inrad 2.5 KC Mech Filter Assembly

[Byron Tatum]

Hello-
    I am restoring a 75S-3B receiver and found the Inrad 2.5 KC mech filter 
PC board assembly plugged in, in place of the usual Collins 2.1 KC filter. This 
Inrad assembly has the Collins #526-8694-010 torsional mech filter. I thought I 
would ask list members their opinion of this filter as compared to the standard 
#526-9427-00 2.1KC filter. Is this a desirable filter to keep in your 75S-3B?
                                                        Sincerely,
                                                                Byron WA5THJ
