Hi Mark - long time! I did not have that luck - the filament pins were actually already shortcircuited. I have the impression that one filament actually fell off, so it didn't leave enough surface to start the tube. I still have the tube - I'll try to do an autopsy tomorrow :) Cheers, John --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
