Re: Testing HV?

Someone once suggested to hold a small neon lamp (the ones you find in
switches to indicate their position) close to the HV lead. If there's any
significant HV it will start glowing. From my experience with small B/W sets
and the vectrex, the HV is often too low to make crackling noise or feel
'static' at the front of the tube. Not sure if this goes for 19" tunes ass
well as I don't know how hight the HV should be there...
