Yours was an Auricap version certainly , like mine originally (tiny yellow caps)
John has been using this capacitor for the last several years and played with Dynamicaps lately. The Mundorf Silver/Oil is a great quality/price capacitor. Many recommended it to me as a better choice in this specific configuration compared to the Silver/Gold. Vcaps would be a good choice as well at a far larger cost though.
Mundorfs have replaced Auricaps in my Exemplar preamp with great results.
