Good point I'll do that when the chassis is out again. Connected up a speaker via the external LS socket and that is fine so there's a problem with the original internal speaker, either a shorting coil or rubbing. I'll get it out and investigate. From memory there may be an adjuster screw but I can't be certain, looks like it'll be a replacement speaker otherwise.
