I've got my CU-168/FRR antenna coupler up and running, sort of. Looks like
the "micamold" capacitors have gone bad. After seeing about 80V on the
output connector when unterminated, I checked on the the caps and found it
had about a 5 megohm resistance.
The B+ passes not only through the primary of the little RF output
transformer, but is also connected to one side of the secondary (to reduce
P-S voltage strain?). The B+ could therefore flow through the secondary and
out through the output jack if the capacitor is bad.
