where can I get a replacement 6 pin connection transformer for a Seimens 750 laptop circa 1990?

Question

It is a metal boxed laptop used by Siemens engineers in the very early 1990s and is a real collectors piece, the transformer being the size of a brick and the whole thing was extremelyy expensive at the time. It still works well, but someone put the six pin plug in the wrong way and snapped and bent most of the pins. Cannot get another as is well obsolete, but like a favourite pair of slippers, can' t and won't throw it out as it has some major research works I have done, still in it.

Answer 1

Call Siemens and simply get the information about the transformer. Ask them to email you a drawing or spec sheet. Chances are that they did not design the power source or make any of the components in the PC so they will probably send you to a another company, for example, Delta Power. In this case you would have to call or email them. Basically you need to know the input and output voltage, current rating, and type of transformer. I am guessing that is a power transformer used for AC to DC conversion.

Once you have this information you can do one of two things. You can call Pulse Inc, Midcom, or Belfuse. They all manufacture this type of component. You can also try Epcos which used to be a division of Siemens who also makes them as well. Tell them you're a contracted designer of electrical equipment for a large company that you can not disclose at this time and you need a sample of these exact specs (gotten from the manf.). They probably have the bobbin (pin), can wind (coil the wire around the bobbin), and use the correct magnetic material to achive the specs you've been given. They can usually turn them around in their labs really quickly if needed too depending on the size and importance of your "project".

The second option is to go to Radio Shack. I have seen stores that sell electrical components like inductors and capacitors for hobbiest but admittedly never seen (because I haven't looked) for transformers but it might be worth a try.

I hope this helps!

Believe it or not, put a request out on eBay.
