The January (I think) issue of Radio-Electronics in the Ask R-E section
has a circuit for monitoring a car battery voltage. I was trying to
understand how the sucker works but get stuck when it comes to the
1N470 zener diode. I can't find this past listed anywhere. Is this a
mistake. The original schematic came from the December 1976 Electronic
Engineering which our library, of course, doesn't have anymore. Is the
1N470 an obsolete part? I sure would appreciate it if someone could
tell me the voltage of this diode.

	Thanks in advance,
