Follow JohCT first with isolation on. You can follow almost any delta tube directions. We did the "just gone line" method.
Isolation is for H-K short. When it happens its usually int. When it shorts the bad guns cathode gets pulled to GND. This makes the screen BRITE of that color
with streaks & retrace lines. You can often LIGHTLY tap the CRT neck
to make it come & go.
SO try a set up & see if you can get a B&W raster. If you cant check the
CRT voltages on the K's, G1's & G-2's for next step.
BTW you can make a universal adapter. You need checker
schematic, cable connector, & those hook on test leads. It can check almost
any jug.
