If triggered once every 8 cycles at 60 Hz, the on-time of the 
Ignitron would be .0625 seconds--if my math is correct--on the back 
side of the curve tapering down to 0 volts.  A better way to power 
the Weldtronic controller might be to use an AC drive, capable of 
providing an adjustable input frequency in the 6 to 8 Hz range, and 
then set the controller to trigger at the 90deg point of every 360deg cycle.

Also, I think the master oscillator should have two primary circuits, 
the original one consisting of the big high tension transformer, 
primary capacitors, and the high-speed and quench breaks, etc. would 
be retained. The ELF pulse generator would drive a second primary 
loop placed above the master oscillator's upper secondary turn on 
insulators as shown in the CSN on page 323 and elsewhere (Corum & Corum).

The master oscillator should surround the extra coil, and not be set 
to the side as was done at Climax when the e-coil was moved out of 
the Oxide Building.  The e-coil itself should be of a high aspect 
ratio, and the elevated body of capacitance should be of large 
diameter and mounted on long, nonconducting legs.  All of this is 
shown on sheet one of APPARATUS FOR TRANSMITTING ELECTRICAL ENERGY, 
U.S. Patent 1,119,732, Dec. 1, 1914 (see 
http://www.tfcbooks.com/patents/tower.htm).  Ideally the elevated 
terminal would be constructed as shown at 
http://www.teslaradio.com/images/image006.jpg and 
http://www.teslaradio.com/images/image008.jpg.  A good earth 
connection would be one or more steel-lined wells, drilled some 
distance below the water table.

Alternatively, the master oscillator and e-coil could be separated 
and provided with independant ground connections and elevated 
terminals as shown at 
http://www.teslaradio.com/images/image004.jpg.  Note that in this 
image a properly tuned Tesla-type receiver is shown standing out to 
the right.  This element was never included as part of the Climax 
experimental apparatus.
