ever heard of the term "regulator hash", or "rectifier hash" -- the Hg rectifier tubes are prone to generating high frequency noise, they are also prone to flashback and peak current limitations...and if you drop one don't vacuum up the little bits unless you have a HEPA filter on the vac -- elsewise you will wind up aspirating mercury vapors and wind up "mad as a hatter".

Yesterday my colleague Frank Verwaal finally tried my high-voltage amplifier with one of his loudspeakers.

Unfortunately, he found that he needs more than the 2kV peak which the amplifier produces for the sound levels he normally listens to.

For what it's worth, he liked the sound very much, particularly the high frequencies. He has the subjective impression that he heard more treble with the amplifier than with a transformer, but also that the sound is much cleaner, with less intermodulation between bass and treble.
