Replacing a Field Coil with a PM Speaker - Please Help
#10

Thanks again everyone for the helpful info. I believe I have it right now, but the speaker didn't arrive yet to test. The output transformer is a Hammond universal, which fits next to the rectifier tube or I may mount to the speaker itself. I have the 1800 Ohm resistor attached to both + for the 8uF and 4uF where the FC used to be and I upped the 4uF cap to 10uF to eliminate the potential hum issue. I really enjoyed rebuilding this first set and I am anxious to start on a 90 next. Thanks guys...I'll let you know how it goes.
