Chris I agree,
	Most of the capacitor banks I use today are the commercial
types. But, I still use a single bottle salt water 500 pF cap in my 
lab. I've had this thing since college, and I still use it today in
safeguarding my power supplies. Its still the lowest cost, energy 
sponge I can find. And as far as safety is concerned, I've placed mine
in a large plastic cup. Even if the cap. blows, glass-saltwater-vinyl
tape and all, are not going to harm anyone.

	For anyone wanting a filter cap for there neon transformer. A
salt water cap is a good RF absorber that can be made easily, while
maintaining good results.

	I do have one question though that I would like to impose on the
community. I've read some previous E-Mail listings, where the sender
makes a reference to his salt water caps glowing. Unless the reference
is to corona outside the caps. Is there a phenomena that I've never
observed in a salt water cap, that I should be aware of?
