Re: Bush A.C.91
Have found an output transformer from a dac 90 attached to a duff speaker , have cut the wires to the speaker. Its measuring 500 ohms primary and as David G4EBT says ,taking into account the resistance in the test leads Secondary is working out at 0.75 ohms ,with my lcr meter i am getting "inductor ,130 uh" ,micro henrys , looks good to go ,though it does need tidying and a new capacitor , whats the best value re Tone for this capacitor ? .Will send Alistair a PM .
