RE: De-Q-ing diodes
Original poster: "Daniel Barrett" <dbarrett1-at-austin.rr-dot-com>
The diode should see a half-sine pulse at a frequency determined by the
charging reactor and primary cap. This is still faster than 60Hz, though not
by much. In theory, the 1N4007 should work, but there is no room for error-
When making my DC coil I burned through about 500 1N4007's trying to get
everything right- The slightest tuning error or a transient caused by a
primary strike would always blow the whole string. With the UF, I have yet
to destroy a string. They are more expensive, but I think I actually spent
more money on all the 1N4007's I blew during the learning curve.

I was just planning to construct a de-Q-ing diode from a string of 1N4007's.
Now I am worried. I thought a de-Q-ing diode basically 'sees' only as
highest
frequency BPS_max, say 400-600 Hz ?
Has anybody experience (good or bad) with using 1N4007's in such
applications.
The UF4007 certainly is 'better' than the common 1N4007, but also MUCH more
expensive (I need at least 40...).
Any reaction greatly appreciated, Rob Maas
