BACKGROUND:
Sustainability is the name of the game! Anything (that has been tested and is still useful) should be repurposed creating saving in wasted Ee and reducing the poisoning our environment when items are buried in the earth at the local tip needlessly.
Never heard of Ee? It is a concept that creates a measurement of ALL things (not just electronics) that humans have made and the energy used in obtaining the raw material, processing the materials right through to a finished product and even should include the shipping of the item to the distributors/retailers.
If you would like to know more about Ee values, please take a look HERE
These EK series Roderstein electrolytic capacitors are USED but have been tested, it is up to the user to judge if it is worthwhile using these or alternately, placing in the component "museum"
These EK electro's stand out from the crowd in their little dark Brown thermoset plastic casing (Yellow underside) and most often can or could be found in well designed German audio equipment (think B&O, Revox & Studer) from around 50 years ago!
Roderstein (Germany) has been around for what seems like the dawn of time, German manufacturers of high quality capacitors and other passives but now a subsidiary of the behemoth, Vishay
RODERSTEIN - Electrolytic Capacitors (Various)
Made in Germany
EK Series
Distinctive dark Brown thermoset plastic casing and if you take a look at where the pins exit the case, it is Yellow. Identification of each capacitor is printed on the top of the casing, and here the + terminal is also indicated.
50 years is an extremely long time in the world of electrolytic capacitors so I have made some basic measurements of each capacitor and the results are indicated below ... it is up to the buyer to establish if these may be of practical use in equipment, for experimentation or as a "museum exhibit"!
