Thank you for your response. The H20 is a 10 1/2inch speaker so I doubt if it was for a portable battery-operated radio. I do have some 5W 1200-ohm resistors and I can substitute in the circuit for the 1140-ohm field coil. I can change the 8uf to a 30uf that won't be a problem. The audio transformer on the H20 speaker is 32-7198. I will see what I can find.
