Depending on the battery damage (leaks), case condition and other problems, I'd probably would keep it for parts and look for a decent working 888 on ebay. Without seeing photos of the complete radio its hard to advise you.

I believe speaker is listed as 3½" but I've found modern units are too large(I believe orig measurement is edge to edge, while newer units are actual cone size). Also with speaker being bolted to PCB, finding one that actually fits is going to be very hard. As already stated, would probably be better to find another radio.

I'm wondering how sunlight could damage a speaker cone inside the radio's case. Please post scans of the speaker and any battery leakage damage. Anything is fixable.

Alkaline battery leakage is potassium hydroxide.
It attracts moisture and forms a white efflorescent crust of potassium carbonate.

Wear gloves and DO NOT get it in your eyes. Scrape and brush it off, and... to neutralize - you can scrub it with an old toothbrush using lemon juice or white distilled vinegar (dry afterwards).


You can post photos as attachments straight out of the chute. No need to wait 24Hrs.
