As far as I know the  best  way to measure the output  of a JT is by rectifying the  output  with a diode bridge  then  charging  a cap  with the bridge .........that is what I was doing .

Thank, so you do use the rectifier only , ok , do you ave a pot , to try to find a better freq , and get more output?

from my previous  post

( edit ......this   toriod  did not  work  without  the a cap  across the  transistor  load  resistor .   I  recommend  using   a pot ..... the  range  that it  work in is  narrower than the black  toroids.
I used  .01uF  and .1uF  the  .1uF works better  )

with  the  cap across the pot  changing the pot  seems to  change the frequency .

I have  tied  changing  the number  of turns  to get  better voltage ........but  havn't  had much  luck yet

@all,
Just had word via my daughter, my wife has been taken to hosp,        seems the other day the pest control fellas decided to spray chemicals inside her unit.
She has COPD, needs a oxygen generator to breath 24 - 7, in otherwords really bad lung disease, she is in intensive care, so I gotta fly in to town.

There really is some whackos unthinking mongrells in this world who don't give a rats, about anyone but themselves, and if they are told to spray, they spray, if she dies, wonder if I can sue the.........off em. (I apologise for the language fellas and Lady, but I'm not tooo level headded right now).

grrrrr

OK gotta go, I will recheck posts when I get time

Hi folks, I have already sent healing thoughts for you and your wife Jim. Whatever happens just know all that we can control is ourselves and as you can see what happens in a world when others wish to dominate and control others, it doesnt work out so well. Stay centered and at peace and the love we give is all that matters.

@electricme,

You seem to have certain ailments - among you and your family - and your relative closeness to airports and other things I now find more suspicious than once before.

I hope everything works out for you both - for the better.
