RE: 19K6100 MONITOR B+ VOLTAGE is LOW.

Joe,
****

 Thanks for the reply, I appreciate it.
Any idea what ZD 901 (Diode) should actually
be (Part wise) ??? Also know of any other
type of Diode which can be substituded for this
particular one, as I do not believe that I have
a Spare ???

  Thanks........
Arcadius....... :-)

The Woodcock faq say this about that range:

15.0-18.0; ZD901 (wrong value)
