Flakey Preamp Housing

We had a similar problem on the preamp housing for our AC 200.
We finally had to buy a new style one ($2500)--all digital--not susceptible
to the problems of the old one. When we got it, it also had a problem, but
not the same problem. I recall having to set up through one housing to do
C13 and the
other to do H1 while waiting for the second new housing to come.

For a while thay had us using an external directional coupler because that
is what the failed housing eliminated for us.
