Hi Guys- I've got a pair of 4333s that I'll be bringing in to my friend's shop for some repair. I've got some credit to burn up with him, and I figured I'd let him take a peek at the innards to get them up to snuff. They've had a very tough life, as I had outlined in a previous post:
Quick version of the 4333AWX's story- maybe 20 years ago Arista records founder Clive Davis wants an upgrade to his office playback system, calls in my boss who he knew through Barry Manilow. My boss pulls out the JBLs, a Sansui BA-5000 power amp, and some other gear. They sit around for a few years, until his daughter turns 10 or so, then they spend a few years blasting Depeche Mode and The Cure through them until she goes to college and can't fit them in her dorm. They sit in her Mom's garage for a few more years, until I rescue them. Sansui goes to my friend Scott:
...to power the Lunar Module Subwoofer in his showroom, JBLs come home with me. Cabinets are rough, one piece of trim on the front completely missing. Moisture damage evident on cabinets, level controls, crossover switch, everywhere. Deep scratches everywhere. Mids sound harsh at certain frequencies, but once they're lined up they're fine. Woofer surrounds were shot, Scott replaced them for me. Still need to clean/replace/bypass the x-over switch, and clean the level controls, but they sound sweet. They'll end up being the playback monitors in my studio's main room, not sure how much I'll bother with fe-finishing the cabs, depends on what I can barter with my woodworking friends. They've been playing occasionally with a Denon PMA920 integrated amp and a Velodyne sub, but will eventually most likely be biamped with two of my Yamaha P2100 power amps.
So, the advice I'm trolling for here is...what else should I be looking for while these are on the bench? X-over switch & L-Pads are on the list, what other functional bits should get the once-over? Any popular X-over mods to consider?
Thanks in advance,
