A multitube gap is a multiple series gap made from a bunch of copper
tubes maybe 3/4" diameter and a couple of inches long. The tubes are
mounted parallel to each other and spaced a few thousandths of an
inch apart. When hooked up, the spark will jump between the pipes
just like a regular multiple series gap made with ball bearings or
whatever, but the parallel tubes give a much larger area for the spark to
occurr over, making it easier to quench it and keep the gaps cool. I've
heard that if you quench the sparks with a high-speed air flow, these
gaps work as well or better than rotary gaps for non-magnifier type
coils up to a few kilowatts.
