BTW for all.........
MOST horizontal outputs ( HOT's) from the late 70's on have a built in
damper diode & base resistor. The resistor goes from B-E & screws up
that reading. The damper diode will give a diode reading E-C one way
& wide open the other on the meters diode setting.

BTW #2
I lied ! I had ONE HOT open out of hundreds I found shorted. In a Zenith
custom series 25".

BTW #3
Quick check of HOT is ground meter & measure C to ground. If shorted
unsolder the HOT's C & retest. if no short its somethin else like FBT.
If the HOT is shorted the fun begins finding out why it did without
blowing parts.
