I have in my possession an old "a/f stage amp" that tops out @ 780 watts per channel ( both channeis driven!).
The outputs are Mosfet (2sk176 + 2sj56) and are obviously in push pull.
I've been told these mosfets will happily go all the way up to 10 Meg.
(it also can be configured as a 1600 watt mono block!)
My questions are,
can I use it to power up a Tesla Coil by giving it Positive feedback to make it oscilate, (It would be easy to tune to the dominant Ferq. of the secondary that way.)or does the feedback coil do that for me?
Can I split the value of the feedback "tank capacitor" and use them to tie the f/b coil to the gates of the Mosfets or do I tie the f/b coil straight to the amp input?
I also imagine that the Feedback coil, would have to be centre tapped to tie in with Class B operation.
Can I split the value of the feedback "tank capacitor" and use them to tie the f/b coil to the gates of the Mosfets or do I tie the f/b coil straight to the amp input?
Also, would I need to use protection Diodes across all of the individual mosfets or just across the P channel and N channel? (4+ and 4- mosfets per ch. ie. push pull parallel )
(So many questions, so little time!)lol!
Cheers again,
Mick. ;-))
