My Dad and I finally got my Wells Gardner 6100 working again after the full-monty cap kit from Bob Roberts and an LV2000, along with a replacement HV board that was a P329 instead of the P316 it came with. Not that I complained, but the P329 contained a surprise...
Word to the wise: ZD is not the same as D. After a couple hours of debugging we found that someone had put a Zener in where a fast recovery diode should have gone (at D901 if I am recalling correctly), and it melted/shorted, making R901 and R907 burn. We found it when testing transistors, and tested the big transistor on the HV box, Q906 I think it is, and the harness appeared to have a short.
The monitor's up and running beautifully, and holy shit do I like vector games now (this one is Star Wars).
