    I used to work for motorola in a past life. It was common for them to disguise parts like Irving said. They would always use part of the original data in the name though so it was just a case of searching using PKS and 32.

    This isn't a drive question but, again this module(Parajust single to three phase inverter) carries coding which is not common for TO-3 Motorola transistors.

    cheers

  3. Educated guess... 2SC901 NPN,.... if PNP then maybe MJ901 darlington (but doubt that)

    Can you tell what type these transistors may be?

    cheers

    Asto please don't confuse me with some genius in component identification. Irving is probably in your best ball park for this one. It was an educated guess with the last one and a power of deduction. Looking at the age of the rest of the components I would not even try to repair this...........There are some limits to when you just have to let go of this stuff. To also put something into perspective i worked in there 900/1800 phone division a very long time ago.

    ...Sorry for making you feel this way. My intentions were not even close to this.
    Well, l can do more reading than writing in the future. Yes, I can do that. Besides, I am not writing in my language.

    Again sorry.

    kind regards

    Asto.

    Just found some sd2 boards tonight, 3 boards, mother board and backplane off a Starmill.
    machine would home and that's all, suspect something on the MB went bad as the axis all moved but gutted it and put everything new in.

    Any idea what these are worth before I bung them on Ebay ?

    My DMM shows these are NPN ones.

    cheers
