Well, so bad the implosion bang is also again; one hears a degree at the small 36 cm Boggle * PLoP *.
Why want to testing jobs the tube at all?
All take out what you need and then point the part easily.
All newer tubes are implosionsgeschützt; IE: If you do want to ventilate the tube (bulb break off), then should the rest remain intact.
The pelting of the spark is that probably a cascade inside in the part. Come mostly from the coil itself only 10 kv with 10-15 mA will hochkaskiert to 40kv (film capacitor switching a homebuilt with 5 nf parallel to the HV-output dan, you have a nice (ung dangerous 3A! no load at 3/4 charged capacitor) bright white blue ARC)

someone has thought time off a fat schweisstrafo to turn around and to bars?
So with regulated three-phase from a fat thyristor Bank?
