[QUOTE="jeallen01, post: 1062429, member: 176704"] Only just noticed this thread and the above in particular - I once had to do some radiation level tests for 30kV projection tubes in TVs destined for the USA (they never actually got there - the company went bust several times!) and the FDA (or whatever it was then)-required tests meant that I had to take the anode voltages up to around 50kV, courtesy of a PSU lent to us by Hunting Hivolt. At that voltage, everything was very "hairy" to say the least - even with the tubes in a specially built perspex enclosure, they were flashing over the dag almost everywhere, and I blew up at least one AVO 8 used for measuring the anode current. Avoided get any shocks myself, but "be very careful what you wish for"!!!:rolleyes: [/QUOTE]
