How useful is a bias voltage that wanders with temperature?
If you have 10 diodes to get about 7 volts, that will reduce by over 1/4 volt
for a 20 degree rise.
Of course, the ZSAC may be so non critical that it doesn't matter on 3-500Zs,
but if you're going to start pushing the output power, carfeul selection of the
right zeners could help.
After all, it's only a relatively few dollars for a number of big zeners - a lot
more for the tubes. even less with 1 watt zeners and a 2N3055 or similar beefy
transistor.
