            I may have mistakenly gotten the description of the Zener =
diode in my SB-221 mixed up in an earlier post. While I was reinstalling =
the HV transformer yesterday I noticed what I thought was ZD-1 missing =
on the circuit board behind the metering panel. There is a stud mounted =
diode mounted to the left of the metering board perhaps this is ZD-1 ? =
The particular diode I thought was ZD-1 is not part of the HV rectifier =
string and=20
will have to take another look see as to what it is.
