Anybody worked on or with UREI 6500 amplifiers

I bought the Urei 6500s mentioned in this thread. So far all have worked; have about ten left.
 
If I had ten amps kicking around I might attempt an odd build... buy a ton of of cheap 6” woofers, I mean like 20-30 per channel x 10 amps x 2 channels. See a car audio build where buddy did something similar. The surface area you are able to utilize on a speaker box is insane. Surface area is where it’s at.
 
I have about 10 left and the ones I have tested work. I'd like to sell them. $500 each; less if you take all. Let me know how to show them to you. I live near Athens GA.

Just looked up one of these amps. Yikes on the price and meh on the specs. Unless it’s of some collectors value to you there’s better options for monster amps. I’m using QSC in my shop system (7600watts of) and my pops has an RMX series as his sub amp. Other than the fan noise at idle they’re great. Hell the carver Pt-2400 I use in my house system has fan noise, turn up the volume or if you’re very critical remote mount the amp I’ve considered this for the house stereo, mount the amp directly below in my basement. Pops got his for a few hundred bucks used, pretty sure is 550wpc at 8ohm 2450w bridged.

So the specs are not that good for the 6500 ?

Is going to be hard to justified another amp to my wife
I already have a few pro amps
Yamaha P2200
Hafler 9505
Hafler Pro5000
Rockford RF2000
Soundcraftsmen RA7502
Crown PS-400

Does anyone have a part list for the Urei ?
The manual only have a schematics, any IC in the amp ? I noticed it uses the TL084 op amp

Got the amp today, yes is heavy, very heavy also, clean inside
The main fuse was out and it was a 10A, it takes a 12A
I need to get the right fuses, if I use lower amp fuses will the amp blow out the fuses ?
Someone chaned the original op amp in one side to a 074, the original is a 084

Great design architecture! Swap out an amp module if there is a failure!
 
Yeah, it isn't going to do diddly without (good) fuses in place.

You could sub lower wattage for testing. I suspect you'll bring up on variac anyway.
 
Well tried a 15a fuse in the main line and the amp power on only one side for a second, and the amp shut it off.
The main fuse is burned. That is as far as I will go
I will send it to my tech for restoration
