>The issue of screen current regulation was a typo mistake ...
// This was an easy mistake to make since good engineering practice is
to incorporate some means of limiting screen dissipation to a safe level.
However, screen current limiting must not happen during normal signal
conditions. If it did, distortion would result.
- However, the orig. statement appears to contain a specious error
instead of a typographical error.
cheers, Phil
