OK. Thanks Axtyr. I'll see if I can check that out.I suppose it's not the end of the world if the speaker doesn't work, just annoys me that's all. Probably not many people use the speaker anyway. I've heard nothing back from Minelab.

G'day Hilux, Thanks for the reply. The circuit board looks fine. No bulging capacitors. It's the actual speaker that's not working. The detector works fine when headphones are plugged in. Just no sound when the headphones aren't plugged in. I'm looking at replacing the the speaker. I'll...

G'day Jaros, you don't have a working speaker for one by any chance?

G'day gef12, It seems to work ok with the headphones, but the speaker in the detector doesn't work. No reaction unless the headphones are plugged in. I understand what your saying. I've had similar problems in the past with headphone jacks and plugs. Not in detectors though, know bugger all...

I'm a dot the i's cross the t's sort of bloke and it annoys me when something doesn't work as it should. Also, I don't like selling things that aren't working perfectly. I'll have a look and see how much is involved in replacing the speaker. Thanks eveybody for your input. Much appreciated...

Hi grubstake, thanks for the info. It looks like it's about 45mm. Bit difficult to measure accurately in situ. Probably pull it apart now and measure it accurately and see if I can buy something close. Thanks again, I appreciate you help. I'll let you know how I get on. Regards, John

After a bit of investigation, it looks like the detector is actually working, it's just the inbuilt speaker that's not working. It works fine with headphones. I contacted Minelab about a replacement speaker but they don't carry spares for a machine that old. It is their first machine afterall so...

Checked the battery wiring and it's all ok. there's power to the circuit board. Can't see anything wrong with the capacitors. Don't know how to check for anything else. Hopefully I can find someone nearby to have a look at it. I'd prefer to sell it in working condition.

Thanks Axtyr, I'll have a bit of a squiz and see if I can spot any damage. I'll let you know how I get on. Thanks.

Thanks ol' son. I'll see what I can find out.

Hi grubstake, Thanks for the prompt reply. Following your comments, I might see if I can take the cover off and see if there's any evidence of a burnt out capacitor. As I said, it hasn't been used for over 30 years and it was working when I put it away. I'll let you know how I get on. Thanks again.

HiI Everyone, First post to PA. I have been "lurking" for a while because I got sidetracked reading different forum posts. Great reading I must say. Anyway, to the reason for this post. Back in the 80's , I purchased a Minelab Goldseeker 15000 from a professional detector/prospector. I'd hardly...
