Okay, removing the electromagnetic speaker and replacing it with a pm speaker. For field coil, I used a 1500 ohm-10 watt resistor. New speaker hums. Replaced 12 mfd power cap with a 16--less hum but still bad. Replaced the 16 mfd with 20 mfd. Less hum still, but unacceptable hum level still. What should I try next. Thanks for your comments!!!
