High-Frequency Coil |
Use this 30cm long High-Frequency Coil to test vacuum equipment for leakage or to excite electrical tubes for demonstrations.
The Teslatype high-frequency coil is mounted in a hard Bakelite case, sized so you can hold it in one hand. One terminal of the secondary is attached to the pointed end of the coil. A screw at the large end lets you adjust it as you need.
The voltage is 40-50kV and the spark frequency is 3 to 4 MHz. The spark length is adjustable by turning a knob. You will need to turn the unit off after 10 minutes of continuous use to cool.
It comes with a connecting cord and attachment plug, for use on 115 VAC. 50/60 Hz.
A version with a built-in on/off switch is also available. Includes instructions.
Not available in Canada.

- Monday, November 03, 2008 Great for demonstrations Reviewed By: Steve Hassett (Portland, Oregon) I've been using these at the Oregon Museum of Science and Industry for years for a variety of demonstrations. It's a reliable model that has changed little since the 1930's (I bought one that old from an antique store - still works.
I highly recommend the version with the button, without it you have to use the adjustment screw to turn it off and on, and when the threads on that screw get worn the whole thing is useless.
