The only thing that is at all problematic to me is that with that design,
you may have up to 3 sets of relay contacts in the signal path, compared
with one set for traditional relay boxes such as the TopTen. On the other
hand, I have used a Heath 4-position switch which often has 2 sets of
contacts in the signal path, for 6 years with never a sign of any
problem. I believe it is quite close in design to the Ameritron RCS-4V
