I'm just starting on the restoration of a 42-355. The original electromatic speaker and field coil had been replaced previously with a permanent magnet speaker. The 1000 ohm field coil in the circuit was replaced with a 150 ohm coil. Also, one 8 mfd electrolytic cap was added parallel with the original 18 mfd electrolytic and another 8 mfd electrolytic was added parallel with the existing 8 mfd electrolytic. Since I am a beginner in radio restoration I am wondering if the addition of the two 8 mfd caps is associated with the speaker replacement. If so, I assume that when replacing the electrolytics I should include the two additional 8 mfd caps. Any other suggestions will be appreciated.
