Hi, I have these old capacitors and wonder what they are?
Can I find "modern" equivalent/improvement? They are used in equalizer module but some are missing. I guess I could replace them with very good new ones?
Thanks for your help

They're just electrolytic capacitors. One value I can read on your picture is 200/25 i.e. 200uF/25V. The more common value these days is 220uF. You'll find the modern caps to be remarkably small in comparison but they'll be better.

Also, there are Vishay/BC Components electrolytic capacitors with same shape (axial).

I actually was wondering about some caps I have in a Spectrasonics 610 that bear a resemblance to these (different brand though). Is it possible that they're wet tantalums?

Those do indeed look similar but I can't recall seeing them with one end potted.

Bob--
In the 610 they're most likely axial tantalums (don't know about the wet part.) Probably RN105D series or something like that.

They are electrolytes from DDR-production. You find them in Neumann Gefell:s and other East-German stuff. The number one inside a triangle was a sign of better or military quality(in DDR).
