"The TL-922 also uses a 4500v Tune-C. To protect the bandswitch from
arcs, I bent the first rotor plate until the breakdown potential
dropped tp 3500v, which is still c. 900v higher that the actual peak
AC anode voltage."
Why, after you install all of the Rich Measures protection circuitry, do you
have to worry about arcing in the TL-922. It would seem that bending the
plate is a useless act - unless there are reasons other than parasitics that
cause arcing.
