Resurrecting a Tempest which had been placed in storage working and came out not.
Have done a full cap kit and rebuilt much of the deflection board. Game has spot killer on and plays blind. For a bit, the game was playing with the screen collapsed to thin squiggle in the center of the monitor, but now the spot killer is on.
Have moved down to the PCB and am getting a steady 7.45v on the X out test lug with pot all the way down. Y seems to be deflecting OK. Good steady +5v from the PS and the rest of the voltage from the ARII looks OK.
Turning the X pot will smoothly up the voltage, as far as about 8.5v.
I'm not very familiar with moving upstream - any tips on basic testing that can be done to isolate the fault - do not have a scope or probe, just my trusty DMM.
Appreciate any help. Thanks!
