No.  Not sure about any of them.

Machine was sold 'as is', not tested and this was how I requested it.  (as a project for me)...Was fully explained and understood by me that machine NOT tested or powered on prior to purchase..I was happy to roll the dice with a BH and thus far (touches wood) has worked out very nicely with almost all components/parts checking out fine....

At this stage I'm leaning towards the fact that perhaps all displays are shot.  Just looking for confirmation on how to test this..From reading the old 9v (and have tried 12v from new cap) and I'm not getting those funky red lines to heat up.  This indicates a problem AFAIK.

I guess its possible that they are all gassed out but I don't know enough about them to speculate..

Solid 60vDC to each connector for displays too.  Grounds buzz out fine on all too...
