Thanks Bill
I have the 1200 volts and the 200 volts. That is one reason for the
question. I don't think the IHVT is putting out enough HV, but I am only going
by the typ of arc which is weak and more like crona than an arc. Healthy arcs
that I have tested in the past would jump an inch or so. Not this one.

Paul, since you have CRT filiments, probably some H.V.... Check + 1200 v ,
comes from T551, thru a fusible resistor, R580 100ohm1/2w, D555 Rc2. to DM
connector to CRT SM .connector Check R580 "open" ? S.M. I have is for a V12B
chassis.. check parts location and values, ! (Caution) ! should be the same!
Hope this helps..
