I have a question for all the amplifier experts out there.
In this schematic:

there is a 250 ohm resistor connected across the fuse/zener. What is
the purpose of that resistor, and why is that particular value
chosen? (I have also seen 200 ohms used.)
I can think of two possible reasons, but I'd like to hear from the pros.
Thanks in advance,
73, Bill W6WRT
