Greetings!

Here is a link to a German language catalog containing the datasheet for the Roederstein EK Series capacitors. See pages 32-37:

I would have added this to the following thread, but it is closed for replies:

Roederstein 'BAKELITE' series EK capacitors - "Living Legend" OR "Looney Legacy" ...?

Hi cap cruncher's !


Just wondered if anyone has ANYTHING at all, to say about these ?

I searched around a bit on the wonderfull WWW...
...but turned up...not much.

I believe they were used in Quad 22's for example...
...and I think Naim Audio used them for sensitive de-coupling duties.

Very old Bakelite has somewhat of a reputation for simply disintegrating & falling apart.
At best not much long term ( we are talking DECADES here ! ) dimensional stability.
However, I believe later...

To demystify the detail of its body construction: 'The capacitor winding is mounted in a pot-like plastic cup and sealed hermetically with cast resin.' (original text: "Der Kondensatorwickel ist in einem topfartigen Kunststoffbecher montiert und luftdicht mit Gießharz verschlossen.")
