Re: [TCML] Another NST question

[Ed Phillips <evp@xxxxxxxxxxx>]

I thought I had read before that nst's shouldn't (couldn't?) be put in 
series to double their voltage, that it would be too much of a strain on 
the secondaries. But, we all know that there's some "wiggle room" in 
their construction, otherwise we couldn't get away with removing shunts 
and doubling the ma output. So assuming that one phases them correctly, 
is it possible to series two of them together? I was thinking 2 
9kv/30ma's to give me about 18kv, slightly less if I don't drive it to 
100%. I just chose that size because I have them already. Thanks 
everyone for your input on this.

   Don't even think of it.  No "wiggle room" at all - the center taps 
of the secondaries are connected to the case and there's not much 
insulation between them and the core or the primary winding.  Hook two 
in series and you'll have two cases at high voltage with respect to the 
junction where you hook the coils in series.  You won't have it for long 
as the insulation will break down.
