Hi Kreso,

I finally got your stuff sent today.  But not the latest ICs...  Still not 
sure which ones you need ?;-)  I have not ordered much DigiKey stuff 
lately, but let me know and I can pick up ICs you need.  More below....

I think "just get the longest arcs" is "perfect" in our case...

If the nicks do not arc over it is just the same as having perfect insulation.

Yes,  Overlaps are really bad!!  The suddenly turn the fields upside down.

No, not at all.

It may run a bit higher voltage with a light load.  Probably no problem at 
all.  Just us thin wire and the voltage at the tube will drop to 
normal.  Best to check the filament voltage directly and add a little 
resistance if needed.  (Whah!!  "Terry" makes a toob comment ;-))

Yes!!

If the diode mess "works" it works....

Cheers,
