I have been looking for the yellow capacitors with red markings that were used on the NTI boards. These were made by Siemens and have their old logo stamped onto them along with 22 / 25 and date, all in red lettering.
Now, due to a stroke of luck, fate or whatever you call it, I suddenly stumbled upon a bag of these. They were even in their original bag and were manufactured in Brazil. The date code is 12.74.
If you need one, drop med a PM (it may take some time before I respond since I don't log in here very often).
