spark lengths are for one tube:   (40% longer for two tubes based on
the square law for spark length)

811A     5"
304TL    15"
813        16"
4-125A    6"
4-250A    9"
845         19"
833A       21"
HF 300    21"
803         12"
3-500Z     17"

Spark lengths will vary with voltage input, etc.  This is just a partial
list of transmitting tubes.  Some of the filaments are not 5V.
