Hi Manfred,
I really like so much your PCB designs that have curved copper tracks !

Also it's a great detail to assign enough space to use mustard capacitors 8)

Off topic: there is an image of the Phillips machine that manufacture those kind of component:

I made a stupid mistake, the chip is of course https://www.uni-ulm.de/fileadmin/websit ... /LM748.pdf

But they probably are compatible...

Jose, I had never seen that machine before. Thanks for posting that... It reminded me of something I wanted to post, but haven't yet... hang on! Yes, mustard capacitors are really high quality they seem to never go bad.

I just found that photograph in the web today and consider attach it to this thread.
I have admiration to see how the technology of the components evolved.

Cheers,
Jose
