EFI....The only way to fly!

I was under the impression that phenolic and Bakelite were two different
substances.  As I understand, Bakelite was the first "plastic" to be
developed, and is derived from wood.   Part of the reason it is no longer
used is because while it is insulative at low temperatures, at higher ones
it is highly flammable.  I thought that phenolic was the modern
replacement, having similar properties except for the flammable part.
(This is just what I've come to understand from poking around in tube
amps)  If phenolic and Bakelite truly are one and the same, I'm not sure I
would want this inches from a glowing turbo EM.
