3200 ohms. Speakers for this set are not hard to find; also, have you considered either having your field coil rewound or rewinding it yourself? Could be that the break is close to the end (not likely, but a possibility)? Just food for thought. If you do go the PM speaker and resistor route, use a 25 or 50 watt resistor - the resistor will dissipate around 10 watts or so, but it will also run hot. The higher wattage rating will compensate for this.
