Re: [TCML] TRUE TC LEAK DETECTOR?

[Frank <fxrays@xxxxxxxxxx>]

Just because the case is painted different does not mean the guts 
have changed. The earlier cases were black and now they are red.

The base is nothing more than a dry type high voltage transformer. 
From measurements, it puts out approx 2.2 KV AC.
The 4 prong socket has 2 pins for the HV and the other 2 are a safety 
interlock. One side of the AC goes on one pin and the other pin goes 
to the transformer. The corresponding 2 pins in the plug are shorted. 
If the handpiece is not plugged in, there is no AC input to the transformer.

The hand piece is a molded Bakelite body about 2 1/2" in dia and a 
little over 8" long.
Inside the handpiece is a complete spark gap Tesla coil!
The bottom has a 2 gap adjustable spark gap that is controlled by a 
lever on the bottom of the handpiece. The gap opening is almost not 
visible and you cannot see difference in the points spacing when adjusting.
The gaps look to be about 5/16" in dia and are mounted on copper 
plates for a heat sink.

The Tesla coil is a conical one wound on a porcelain form. About 1 
1/2" at the base and 3/4" at the top. The actual cone is about 1 3/4" long.
The secondary is super fine cotton covered wire.
There are 2 slots in the base of the form and this is where 2 caps 
are fitted. They are about 1 1/2" long, 1/4" thick and 1/2' high. 
They appear to be a sandwiched mica type.
The caps measure 0.003 mfd each.

The HV comes up to the handpiece thru 2 HV wires and connects 
directly to the spark gap. Each side of the spark gap goes thru a cap 
to the primary of the TC. So, the gap is in parallel with the HV 
transformer and the primary of the TC is coupled by a cap on each 
side in series for each end of the gap.
The low side of the TC is connected to the top winding of the primary.

The coil throws a 1/2" to about a 1" spark, super purple in color, 
HOT and the coils just about gags you with the ozone it throws.
