Hello again,

Maybe the cathode resistor is correct after all, but if you only measure 0.5 V across
it, it means current is only 4 mA, definitely low.

(What I meant here is that sometimes component values are changed in production).

The jumper you see at the CRT pins connects the focus pin (6) to either pin 2 or
10, as selected for best results when installing the CRT. This is no problem.

I think I will call it quits for today, don't give up hope, the diagnosis will come up,
and the cure will follow! Let me know what you find out, but as I just said I won't
be replying until tomorrow. If anyone else wants to join in, I trust you're welcome.
