I thought I had this monitor working, but I thinking a bad harness blew something
both 3A fuses (F600 & F700) on the deflection board smoked and C901 in the HV
I put new fuses in and a new C901
all 3 smoked again....
I pulled all the board check the transistors on HV and deflection boards they looked good. (still gotta check all the chassis transistors again
What would make C901 fry? bad flyback?
the gameboard (tempest) works fine with output on X/Y to my scope
I have LV200 Lite installed as well both leds are on it and not spot killer LED -- no chatter either -- so I think no HV
