tubes for tube coils

Gary,

To find tube coil tubes on eBay, do a search for such items as:
transmitting tubes, transmitting triodes, power tubes, power
triodes, etc.  There are usually a number of them available.
Often the 4-125A tube is offered, which can give a 12" spark.
This tube is often reasonably priced.  Various other tubes which can
be used are; 4-250A, 4-400A, 3-500Z, 304TL, 304TH, 833A, 833C,
813, 845, 805, 810, 811A, 812A, 3-1000Z, 4-1000A, HF-300, etc.
I show some schematics at my website (click on the various links).
