Thanks to the generosity of Chuck Harris in loaning me a manual, my HP
107BR is now back in service, or at least warming up back to a stable
state. Shorted Zener diode (CR2 32 volt) and burned out series resistor
(R1) replaced and all OK again.
I have made three extra Xerox copies of the manual (2 side to 1 side,
double copies of schematics), that are now available to whoever needs.
Please advise.
