[R-390] 1. Re: R-390A balanced input question (Craig Heaton)

Jim,

When you have the time; look in the Y2K, manual Chapter 5, figure 5-18. The
balanced input has to pass thru many more switch contact vs. the unbalanced
input. So if using the unbalanced input the receiver works, then the problem
will lie between those switch contacts, most likely dirty contacts. 

Nothing one afternoon, a six-pack of your favorite brew, Deoxit, and elbow
grease can't fix.

Craig,
