In the Thread: How to get a LOT of SET power.

Post Subject: HAHAHAHA!Posted by N-set on: 4/17/2011

Please, guys, I'm not an experienced builder at all!!Please don't offed a real experienced builders!
I'm rather both hopelessly stupid
and ignorant. Knowing that, I'm trying to be carefull. That's all.
My active participation here, apart from the spiritual motivation to hear an unheard trace
of the voice of God, is simply because I have an unfnished, idiotic, lifetime project over which I've
spent countless hours, down to designing the PS transformers myself and getting
German EI laminations for them. Then the experience came from my winders, they've showed me
few tricks. Now that project may get a new, less idiotic, life now. At least on paper...

Paralleling: good points! Although this is the transformer which changes V's to A's, but true
a tube like 6c33c is somewhat closer to that function than many other tubes. Parallel drivers would
have to be matched, which with 6E5P will not be costly.

2-3kV: I look at those Wavac's ect to see how they protect the tubes. The topcaps
are fully covered, probably in teflon. If you touch whatever part, including the tube, you are
potentially safe from HV. I'd add a faraday cage around the tube. Not only for safety but also to shield
the strong fields from the powertube. Inside: HV potted transformers and chokes, RF HV cable (I have 80m of
a prime RG something, good to few kV). This also answers Paul: use RG coax for the connections.

And I'd definitely try Slagle's cancellation technique in the OPT too: an additional winding
carrying 11A of the heater current to cancell some of the 350mA DC magnetization.
This should make the OPT even more tangible: low effective DC magnetization, no MF nor HF,
just power and inductance. The magic of DSET.
