I am turning a M8000 into a M8500. I did the anamorphic mod to the verticle board and installed the entire 8500 rear heatsink unit to the 8000. Not sure what other parts are original to the 8000 as I have bastardized several Marquees over the years.

Anyway, when I powered up the green looked fine, was dark except the "No sync" message. But the red & blue were lit up bright, they should both be dark with no signal present.

I remembered to pull P14 before I powered down, so no spot burn occured.

I have not had a chance to try another verticle board yet. Is that most likely the culprit? In what conditions will a tube's raster run hot like that?

Sounds like the G2s are set too high. THat's all.

Oh right, that makes sense. Those values are probably held in the control board which came out of a very high hour machine.

Thanks!

Correct. Ramp those down and you'll be fine.
