When I last tested it (still using Frankenswitch v2 in the setup), it looked good except for VHF-LO, channel 6 -- lots of noise (or reduced signal) on that one.

It was set aside for the summer, since the electromechanical v2 version works fine. But today I was repairing the pre-amp, and took note of the capacitors used there. Thus the query.

Thanks!
