If all the DC voltages are correct you should get very bright service

& test good but be a little weak.
Good news ! Since I was a bench man & only did about 25 of these
sets I ran it by our old road man over a beer. He did a repair on
one once & it had the exact same jailbars. Bad news is the set was
very old & they didnt want to pay to pull the chassis. At least you
know this wasnt self induced & a real failure, possably common.
Just for kicks remove the wire from service switch that go to
jcn of R295 & R297. See if they go away.

Okay, Sunday is the day to disconnect the wire from the junction noted to the switch. So I am to leave it in normal mode without that lead in order to see if the switch has a bad connection and might be allowing current from that lead from the setup side to the normal side, right?
