Swarfing, how did you manage to get to the TIP32C which is the best replacement without real data of the old transistor. Because PKS0320 is not a valid code for this part. I did not know this when I started this thread.

It is printed on the old transistor but it has to be something like irving said. This code does not belong to any known transistor family.
Anyway my SD2 drive is alive again and runs fine.

Now I have to see how much hope do I have to fix the problem for my x-axis stepper motor losing direction.

cheers
