Ok Jim. I took your comments in good faith, once
you get in the realms of 2KV one does need to be very careful. I will keep you
posted with progress, the first task is to have the PA working with 1200V, then
move on to 2KV.

Sorry Ken,
I did not mean to
trivialize or be facetious but microwave transformers do have a reputation for
biting. I will refrain from further obvious comments!!

There will probably be a fair bit
of technical smoke comimg out of Luton, but
that is what our hobby is all about, any other usefull
sugestions?

Does any one have experience in
using microwave oven transformers in high voltage power units, I acquired
two of these at the weekend. I was informed that as they stand the voltage
regulation is poor, to improve this the 'Core Shunts' should be removed,
(these are laminations between the two stacks), removal of these 'shunts'
also has the effect of considerably increasing the magnetisation current.
The solution to this seems to be to use two transformers, connecting the
both primaries and secondary's in series to restore the 2KV output
voltage.
Any comments on this most
welcome
Note for Mal, this is serious
stuff not for appliance operators.
