The rest of the family is almost ready to head off to

The SB-101 sounds interesting, I will check it out.
I suppose I do not have to use the matching power supply,
there must be something with the same specs that is 100% non-semiconductor.

I'd hate to go through all of the trouble of acquiring
and optimizing a no-semiconductor rig only to have
something in the power supply fuse in the face of EMP!

OR, is it fair to say that the semiconductor devices
used in the matching SB-101 supply are of such high
tolerance that indirect EMP won't bother them?
