Re: [TCML] DC SGTC charging inductor

Agreed times are changing in that

I understand some have used the inverter supplies successfully as high 
voltage sources

Here in NZ old MW ovens are still reasonably available BUT you do need a 
good relationship and some trust from the repair shops as they don't want 
their cast offs coming back repaired or anybody getting hurt. When I got 
mine I had a good chat with the manager of a repair shop so he knew I knew 
what I was doing an none of the "junk" would be repaired. Still it's good to 
know their scrap value is recognised so it does not go to waste

PS the big coil is 14 MOT's in size, 6 in the PSU, 4 in the DC filter and 4 
in the ring up ,heavy too.

Speak for yourself, Tesla  ;o)

Around here, the local waste transfer station won't let me take old
microwaves any more, 'cause they say that their scrap value is too
high.  Only time I can snag an old MWO is if I see one that someone has
left illegally at the curb on trash day, and even then, they don't last
long.

On top of that, the newest ovens use high frequency solid state inverter
circuitry and a small coil resembling a glorified TV flyback transformer
instead of the old big iron MOTs.  Utterly useless for TC  applications.

Grab those old MWOs while you can!
