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.

To e-mail, change noise into sound.

Unfortunately the cone is fine, but the coil reads several megaohms.
