no effect at all, at least it still works.

Still under scanning.

The adj calls for zero beam current, adj horz bias for 25.3kv.

Not sure how to get to zero beam current, what I have been doing is turning brightness all the way down, screen drives all the way down, and CRT bias all the way down to get as dark a screen as possilbe. With the Horz bias turned fully CW I can get the cathode current to 220ma which is in line with the sams. I am reading this with a simpson 260 bypassed with a .1uf cap.

when I turn up the brightness to a normal viewing setting (screen up and crt bias up) the cathode current goes up to about 320ma max (it varies with the signal).

that just seems high to me. AND I still lack full horz sweep.

voltage reading look good now that I am using my VTVM, the DMM was just not giving me good readings. There is a 4200 ohm 2watt resistor in the yoke (Y-107) but I cant imagine that being an issue.

Next up will be the drived voltages to the HOT on the scope.
