did a quick test, maybe 2ma drop but that could be anything. Of course I don't even know if the convergence board is functional so just plugging it in really proves nothing at this point.

the horz osc has an annoying problem with not alway starting, I can see the current spiking, a quick fiddle with the horz hold coil and it starts right up. I hope its just a tube issue. I could not see any loose wires on the hold control.

I will go back and reflow everything on the horz board if the new tube does not do the trick. It seems like it would have to osc, unless something is biasing it off on startup (gassy/weak).
