Dave,

OK, your mag-quench gap sounds very good and interesting.  Please share with
the list enough detail that one versed in spark gap construction could build
a similar one for experimental purposes.  Do you also use some forced air
cooling with your gap?  How does performance compare with the more common
static and RSGs?  What KVA level is your coil using?

Thanks,
--Steve Y.
