    I'm working on a project involving a 1950s Conn organ and have come across a ton of Fast polystyrene capacitors located in the tone generation circuits. This is a name I've never seen before and can't seem to find any information about them on google. Has anybody heard of this manufacturer?

    It appears to to be a hyped up polystyrene capacitor. Today's polyester and polypropylene can match its specs.

    Are some of them bad or are you just curious?

    Thanks for the replies. I haven't run into any bad ones, but my intent was to just replace all the electrolytics before they fail and short out, not so worried about tone caps until they go bad. I hadn't heard of the brand and was curious. I've found some bumblebees, blue molded mallorys, dominos, and also a bunch of good alls, so it's been an interesting mixture so far.

    I'm confused. Correct me if I'm wrong, but wasn't Solen founded in the 80s? These capacitors are circa 1959. And mine are polystyrene and those in the link were polypropylene.
