Hi!
It looks like I have an issue with one of my Orac's stepper drives (1983 machine). I have located a faulty power transistor TO-220 package. Printed code not completely readable. <PKU xx xx> two separate two digit numbers and date code 37 82. No way to find it.
Before this last breakdown, a CMOS IC caused failure as well. The CD40106. I had then replaced that and the drive worked again.
If anyone has one and likes to sell please let me know. Faulty drive is o.k. with me. After all, I only need this for the spare parts.
Thanks
cheers...Dimitri K.
