Deben Mk1 issue

[EDDIE B 3,170]

Lads, I was recently given a Mk1 box, which does work, but the sound is very low. On a calm day, it wouldn't be much of an issue, but on a windy day, or near busy road, it would be problematic. 

Anyone know what the issue might be? Is speaker fecked, or might it be an easy enough issue to fix?

I had to have speaker changed on an old mk1 box years ago, mate who works in a school technology dept done it for me, but said it was simple

Have a look at a smoke alarm you stick on the ceiling i grabbed a couple being scrapped needed the battery connections and sure i got a speaker out of one as well 

You have checked the solder connections ?. some just dry out and need replaced

Done nothing yet except opened up for a look. I think that's what I'll try first cheers. If that don't work, might get a speaker for it, and try that

Finally got back at this, and still stumped. Took off the speaker, and tested it separately, and it works perfect. I also un-soldered and re-soldered all connections, but made no difference when everything was back together. I was actually hoping it was the speaker, because that's easy solve. I honestly dont know where to go from here, because like most, I know nothing about circuit boards etc.
