Hi All,
My big coil (22" sono tube) is on the back burner but I am considering my
various coil projects as a whole. As you all know by now it is hot as hell
here and very dry! (So Ca) A good time to wind or at least coat water
soakers...
I have a really nice, new 5KVA PT @14440. I also have a 5KVA pole pig.
Both
support 240v in. Just adding a second current control slide and stacking a
2nd voltage control 1256D will deliver ~14400va from my control cabinet.
This is my ideal voltage/current for charging .2uf (2 ea paralleled, new
.1uf GA 1000pps caps) to a .5 inch primary. Asrg will run btw 200 and
400BPS.
Do you think this combination of transformers is ok? Otherwise I will need
yet another 14400v at 10 or 15KVA (I have (3) 14400v 5kva units, one dry,
one in the pole tank, and one nicely potted PT).

PS The DIY filament transformer works great! I can deliver 50amps @ 10.4v
(measured with 2 current clamps and a DVM for voltage) without breaking a
sweat.
I plan to add a few turn and add a 12v tap. I can tell where I unwound the
#6awg (was 12v) before I cut it. I'll post a couple of pictures and
document
the turns when its done. My only wish is that I would have joined the
France
E cores before I wound the secondary; as there is almost 2" gap between
the
primary and secondary on the core. I guess I may need a weird tap in the
future - lots of room! So save you dead 15/60 France Transformers. I bet
the
sign shops have lots with a good primaries for disposal since GFP. BTW the
primary of the France I had was aluminum under the coating as are my MOTs.
I
bitch to solder if you don't move really fast after cleaning the aluminum.
