restoration project on JBL 4310

[bikehomero]

Hi, my name is Jürgen and i'm new here since i've got a pair of old JBL 4310 monitors. They are driven by 2112, 2105 and LE20-1 so the later version.

Cases have dents, scratches and are crudly made. You can cee nailholes and poor paint application. One of the tweeters ist damadged, it has only 1,2Ohm.



First the glued bezels from the bottom edge and the tweeter must be removed to reach the screws among them. I've used some heat and a sharp knife.

Beautiful job Jurgen! I hope you can find a new LE20! I saw a pair on Dutch Marktplaats some time ago.

Was it only primeror was it a primer with "spachtelmasse" (putty) in it?

[bikehomero]

Yes Martin, it was a primer with putty. I've allready got a pair of LE20-1

Thanks for the answer, I have a pair of 4301 cabs in sad condition so that kind of primer should work wonders. I already repaired 4 completely chipped corners

Some work with the veneer:

More veneer. 10x oiled with ever becomes finer sanding up to 600 grit:

I love well documented restore projects like this one. Always pickup up some tips
that can be useful later

the veneer looks like oak in some pics and like walnut in others ?

[bikehomero]

It's walnut.

Very nice job!

Know i'm ready with the woodwork of the first cabinet. The new LE20-1 has an impedance of 4,2Ohm, seems well. So i put the drivers in again to try it. L-Pads ar only treated with T-6, better cleaning will follow soon.

Works well!



It know looks better than ever, evrything, including the baffleboard is supersmooth.

Ah, smooth like baby buttcheeks? Nicely done!!
