Why doesn't negative voltage work?

[d3x0r]

That's not to say it doesn't 'work' it uhh.. does strange things with the biasing...


like why is the collector -27V? shouldn't be more than -12?
----
went back and added more notes of known values; the transistor doesn't seem to matter... larger volt/amp seems to be better... though... right now... I'm getting decent voltage output with < 300mA input..... so maybe I can even go small signal...


87uH coil resonates at harmonics of 16Mhz (4mhz, 1mhz, 528Khz) I can use any of these to get voltage output... lower frequency is higher power transfer (higher current similar voltage)


------
This is all really Ruslan stuff simplifed to just the kacher and coil as last demonstrated...   just got to a point that I seemed to have decent output; but the 1Mhz frequency is messing up my meter still... even through the diodes and capacitors...

I have a similar sim from falstad probably...


first image: (this uses signal generator instead of kacher... )
second image: not kacher either... but mazilli; extra complication for series resistances... so in some ways my 'napkin sketch' is better.


was also testing my new digitizing input thing... learning new hand eye coordination; and I dunno... maybe cause it's my handwriting it's more clear to me...
