Hi Folks

Having some trouble finding some transistors.

I am repairing a switch mode power supply and have a number of transistors that need replacing. The issue is I can't seem to find them online....maybe my google fu is out of whack or I have forgotten something obvious.

Any way there are 3 different types of transistors

first is marked as follows

2001
-2J

Second

2005
-2I

third
P4M
25

if anyone can help me out or point me in the right direction that would be greatly appreciated.

Hi,
you might want to post a question on vcfed's forum:

Someone there could have a (even partial) schematic of that PSU and help you getting the right replacements.
The closest SUN workstation that I have at home is a SS10 so I don't think there're chances that it uses the same PSU as the Classic.
By the way, what's wrong with the original parts?
