Yes, and they can oscillate, and they take up a lot of room, and they get 
hot...but they are so purty. :-)

Yes, but those effects are a lot slower.

Yes, but stabilizing the voltage will eliminate some of the mechanical 
instability.

I checked Mouser and 5 and 10 watt Zeners are really, really cheap and take 
up a heck of a lot less room than VR tubes....but they are so darned ugly.

Still, the power supplies I have here for the receivers are pretty compact, so I 
may just go with Zeners anyway. It would sure be simpler.

Might as well make the power supplies as capable as possible. It will come in 
handy down the road.
