elemenoh Posted October 22, 2020 Report Share Posted October 22, 2020 (edited) This IIci speaker is non-functional. A known-good speaker from a SE works okay when attached. Reflowing the joints for the voice coil wires to MLB connection wires didn't help. Neither did spraying the connector with contact cleaner. The voice coil wires seem like they're attached okay. Is there anything obvious to try before tossing it? Edited October 22, 2020 by elemenoh Changed model number from IIsi to Iici Quote Link to post Share on other sites
ymk Posted October 22, 2020 Report Share Posted October 22, 2020 Measure the resistance. It's not worth risking the audio circuit over a questionable speaker. Quote Link to post Share on other sites
elemenoh Posted October 22, 2020 Author Report Share Posted October 22, 2020 @ymk It's showing OL on this speaker, but I get a good reading on the SE speaker. Does that indicate a break in the voice coil? If it's beyond repair, is there a modern replacement with the same dimensions I could swap in? The SE speaker is fine, but it'd be nice to replace it with a speaker of the same dimensions / specs. Quote Link to post Share on other sites

kiag Posted October 24, 2020 Report Share Posted October 24, 2020 I can probably send you a IIci speaker. I have a busted up case with the speaker still in it. DM me if you need it. I’ll have to test it. Also, I might be a little slow because I’m going to be on the road a bit, but your profile says CA, USA. I can send it to you US Mail later in the week.

techknight Posted October 26, 2020 Report Share Posted October 26, 2020 Yea open voice coil. 2 possibilities. one, the glue becoming acidic as it breaks down, could have corroded and opened the coil. Two, when the caps went bad the speaker saw DC and opened the coil . either way, the speaker is blown and now junk. Quote Link to post Share on other sites
