Every horizontal tube except the HV rect. and HV reg. was either weak(osc. tube), shorted(HOT and damper), or missing(focus rect). With new tubes it don't want to make more than 1KV of HV. It does not do any better with the horizontal plate drive signal from my B&K 1076 so I suspect the damper area is the problem. Wish I had a schematic for this set so I could troubleshoot the horizontal easier.
I also sold everything I brought...It surprisingly paid for everything I bought except for 3$ of LPs  I'm over joyed that I effectively traded stuff I've lost interest in for stuff I want with a net reduction in physical volume of sets coming back home. |
i have the same zenith ,it still needs some work but its the same everything. the sams is packet 757- 4 i just got one for mine ,after i replaced the crt connector and hor. plate cap wire i see it needs a complete recap. job.
