I am restoring a Peerless reproducer, components include a square box which I assume is a capacitor, a coil, and the horseshoe magnet. What would the value of the capacitor likely be inside this box? Can someone advise how these speaeakers were wired? I am assuming the capacitor kept B+ from going through the speaker.

It's been years since I looked inside one, but they may have used 10kHz whistle filters, pi networks with a coil and two capacitors. Those wouldn't keep DC from the coil. The caps weren't very large. You could disconnect the filter.

On the other hand if it's a large paper capacitor it probably is in series with the driver coil.

It does look indeed that two capacitors were intended with 3 leads coming from the tin box. Any suggestion as to what to repalce them with? .01 ?
