RE: G05 802 help please

I actually have a Fluke 12. Yes, it does rock! I bought it about 7 years
ago and have only had to change the bat once. And that was last year!

I have checked all my transistors; they were all put in the right way.
Thanks for the tip. Another board I had did have them backwards.

At this point, I still have yet to figure it. I know the chassis
transistors are good as a working deflection board works fine in this
chassis.

Any more ideas? Maybe something in the power supply? I'm kind of at a
loss here.

Are you sure your meter is capabale of detecting 'leakage' in
transistors?

you may well have bad transistors, but your meter can't see them as
bad...

I changed my meter when i realised this.. the Fluke 12 rocks...
