Glad you liked the idea, Bob.  It would be kinda fun to
see how far the idea would go.  I'm thinking the best
configuration would be to have 10 - 20 LED's in parallel
with current-equalizing resistors to balance the load,
and maybe a big zener across the LED's to prevent
excessive voltage drop across them.  Also give the whole
plug-in replacement module a 'May West' shape just
like the old 866's.

You've also given me another inspiration:  simulated
anode incandescence in solid-state amplifiers using
red and orange LED's.
