[TCML] TRUE TC LEAK DETECTOR?

[Ed Phillips]

    Wonder if anyone has any information on an ECCO leak detector 
apparently made during the 1930's?  Unlike the Cenco and other 
kicker-coil type "Tesla coil" leak detectors this is a true TC.  
Consists of a box with the HV transformer in it and a regular  4-pin 
ceramic tube socket on the top.  The lead from the coil plugs into this 
socket and runs to the coil assembly, which has an adjustable spark gap 
in series with the primary of a conical coil.  Works is contained in a 
ventilated bakelite case not unlike the Cenco units.  Wonder if any 
other similar units were built.  Seems more complicated and dangerous 
than the kicker coil...............
