What is DP8? - Macintosh Analog Board
Posted by: cfriberg on 2018-08-17 13:45:28
It's been recommended to replace DP3, DP4 diodes which I am ordering.  They look fine except the solder joints look burnt.  What I can't find is DP8.  It's a little diode maybe similar to DP3.  I can't tell because it burned up.  The 1st picture is just my board model.  The 2nd shows DP8 under that blue cap.   What is this called, so I can order a new one?

Thanks for your help!!

removed one from the board to check the markings,

the diode is a

PH-73D

the resistor next to it is 10 ohm

Took me some while to find the exact diode type. It's a philips BYD73D. In fact, I just registered just to write this here. You won't find anything by searching for "PH-73D", so I looked through some old philips components catalogues.
