This would be a suitable resistor location on the Zener's prepped for installation. (Remember
one Zener for amplifiers that have a string of bias diodes.)
(Fig. 24)
There was an intention in revised boards to supply +24 to +30 Vdc as a reference. There is a
pick point for this 100K resistor on the later boards. The tap point I provided for bias or
accessory use can be identified by looking for two small rectifier diodes near one of two small
electrolytic capacitors. If you have the back panel down and can access these points, they are a
slightly better point for the 100K resistor. This is NOT a mandatory point; it was just an intended
production point when we were having problems with some early Chinese early 811 tubes.
