Re: Introduction & Tube 833A



Hello,

Well you are asking at the right place for info on Tube coils, as there are
many tube guru's on this list. I have done some work with 833A Tube coils
this year with good results, and as time permits, plan to do more. First,
if you see my web site at: http://www.pond-dot-net/~davidt and follow the link
to Tesla coiling, you will find a link for photos and Tube coiling, see
both. I have the RCA spec. sheets for the 833A available, and some tube
coil schematics, etc. 40 usd for a brand new 833A tube is good, I have
payed $20 for used ones of unknown past. Let us know what kind of coil you
want to make, what your power supply is, etc....

Regards,

David Trimmell
