    Need help with a restoration speaker crossover plz

    Anyway... (I will try to keep this very long story short)

    I am helping to restore a 1961 Fischer Statesman stereo console. The preamp/tuner and the separate amp are out of the console itself being recapped among other things by a professional repairman. I have tasked myself in the replacing the remaining original wires and such other things remaining in the console.

    As you can see the very simple crossover has two capacitors: a paper one and a mylar one. Now I have plans on replacing both of them but have never heard of paper capacitors. What type of capacitors should I replace both of these with? Should I stick with mylar or something else?


    Now what really has me baffled (pun intended, lol) is the rest of the crossover. On the back of each speaker there are two potentiometers. One is marked Presence leading to the midrange driver and the other Brilliance leading to the tweeter. How do these two variable resistors affect the crossover? Do they change the slopes or x-o points or just the individual volume output?

    Regular poly/mylar caps should be fine. Do the pots still work?

        I think the pots still work. We will see when everything comes back from being restored.

        Thanks for the links. It saved me the trouble.
