Hi Howard,

I'm interested in these preamps. I have an MKU232B coming from SSB USA. Did 
you have the front end filters retuned? (Maybe you have the gear to do it 
yourself ?) Gerry @ SSB is resetting the filters in my preamp for 2401 center 
freq. I see the SP13 specs 2300-2400 and the MKU232A is centered at 2350. Not 
sure about the MKU232A2...

Please keep us informed on the performance. I will do the same when I install 
the new preamp soon.
