[ARC5] "Curing Chirp in Command Transmitters"

We can blame it on:

1.  Old age

2.  Not enough coffee

3.  Fat fingers

4.  Sleep typing

5.  Temporary Dyslexia

Glen,

You're correct, of course.  That was a typo that I hadn't even noticed until your reply.  I meant 1626, not 1629.

Forgive me, but the 1629 tube isn't even needed to operate the transmitter when the heaters are rewired for 12-volt operation and, if the proper resistor is added across pin-2 and pin-7, to compensate for the current draw of the 1629 heater, or the value of R-71 changed to accomplish the compensation, then running with the original heater wiring works without the 1629 being installed.
