by the way,,,there is a jumper from the base of the HOT and the trace
that goes to the driver transformer. It is right near the HOT. I've
found many with this " loose connection" and now when I do any of these
sets (ctc175-ctc187) I solder this as part of the general chassis solder
which includes the tuner grnds, horz driver transformer etc.
