90 volt power supply?

[Old Tone]

Happy New Year to all. I want to build a HT power supply for an old vacuum
tube transmitter. I need 90 volts at about 30 ma. To run from a 7.2 nicad or
similar. Does anyone have a circuit or suggestions. I know that I probably
need a multi vibrator with a step up transformer but have no idea of component values. Cheers. Tony.

You will have more luck if you post in the DIY Electronics part of the forum.

Tony- If you're handy with a soldering iron, You'll have no trouble with this kit- http://www.tubesandmore.com/ I put one together a couple of years ago, and it works great. Go to 'Kits' and click 'Power Supplies'- Jim

Tony- I'm sorry, I didn't notice that you live in the U/K. My above post won't do you much good. Jim

i've got some old (60's) rcme's with circuits to do the very thing!
will dig them out and scan and email or pm.
will take me a day or2 though so some one else might beat me to it!
