Excellent purchase!
The extra pages of calculations and schematics sound especially
interesting ... perhaps you'll be able to scan them and make them
available if they are of general interest?
One serious problem I have with the SX-28 is its weight. The thing
is incredibly heavy. Just moving it around on the bench is a struggle,
let alone carrying it any distance. The risks of bending or crushing
parts, when you have the chassis out of the cabinet, is considerable.
I'm seriously considering picking up an old Tek scope cart just for the
SX28 :-)
