Hi Wade:
The following is strictly my experience FWIW.

I built a 900W coil last year strictly for use in a local haunted house.
The coil uses an Allanson 15/60 and a 9 copper tube, parallel static gap <no
forced air> MMC etc.
The Hangmans House of Horrors has a rather vigorous schedule. On those
nights it is open (most of October), the coil would be in use about 5 or 6
hours per night. The duty cycle typically was 1 minute ON then 2 minutes
OFF. It varied a little depending on crowd flow. There were times on a
Saturday evening that it seemed as if it was 1 minute ON and 10 seconds OFF.
It worked well and the 1.75" diam tubes never got warm.
The only drawback, also noted by others, is that under such conditions, the
tubes get oxidized within 2 hours of use. The 24-30" sparks dropped down to
6 inches as 2 hours approached. But 5 minutes with crocus cloth, "flossing"
them, brough the output back to 100%.
This year I am replacing the copper tubes with 9 tungsten carbide donuts,
Smaller and they don't need flossing.

Safety First (careful of drill presses)

Hi Guys,

I'm a little disappointed in the response that I received about how long
will the TC operate???

I've spoke with a couple of different people here in Omaha, and they seem
very confident that TC's operating with static or rotary gaps can run for
very short periods of time. Where a solid state driver is more reliable.
I'm hoping that you folks will clear this up for me???? Please.

Onto a good question.....Will matching the impedance's of the primary and
secondary coils increase effeciency and performance of a TC??? Or is it
even necassary.

Anyway, Thanks

Wade
