as you can imagine philco speakers arent readily available anywhere let alone here. i have a line on a 60 speaker im trying to shoehorn into my 84b. the parts are the same on each speaker except the field coils as they carry different part numbers and have dfferent currents 84=50ma,60=65ma yet both have the same resistance value 1140 ohms so inductively they must be different but both use a single 42 tube.to my mind it should work,BUT WHAT DO I KNOW??? is this feasible?
