My manual is a Revised: November 2000. The Document number for the
schematic, Q30102000E Rev: A Dated February 17, 1992. It looks to me to be
the wrong schematic for my PCB board. Maybe some one might know if it is or
not or have the correct one that they can send me?

All it says about the diodes is that they are either D5, D7, D9 etc. It
doesn't say what they are.

Yes, it doesn't say but if it were me, I would replace the
blown diodes with 1N4148's (assuming discrete diodes will
fit in the SMD pad space).
