Heathkit clock speaker?
"Dave Plowman (News)" wrote in message ... In article , Joe wrote: I just managed to get hold of unbuilt Heathkit alarm clock GC-1107. The electrolytics were dry and the speaker is shot. Finding replacement caps was easy, but does anyone here know the impedance of this 2,5" speaker? Is it "normal" 8 ohms or something more exotic? Presumably it's the cone which has gone? If so the coil should still be ok so measure the DC resistance. That will be near enough the impedance for a guide. Early small transformer less (output) small transistor amps sometimes used 35 ohm speakers, but they got round this when silicon transistors arrived. -- Small asylum seeker wanted as mud flap, must be flexible and willing to travel Dave Plowman London SW To e-mail, change noise into sound. Unfortunately the cone is fine, but the coil reads several megaohms. -Jan |
