Sorry all, I have an emergency at work today and won't
have time to write much.  I did think of a couple of
"Pro"s I forgot yesterday:

	No semiconductors
	No active components
	No hard-to-find or exotic components

Depends on what you mean by "easily".  It's not a plug-in
like my 3DW7.  You'd have to drop the front panel, unsolder
three wires, remove an assembly and the new S107, remount
the old S107, and solder three wires.

Geez, tough crowd.  If you're serious, Cecil, nobody's forcing you.
I never thought of it as a diagnostic, tell me more.  Nah, you've
gotta be kidding...

Back to the emergency, believe me I'd rather stay here.
