    JBL/Urei SR6670A

    Is anyone here familiar with JBL SR6670A? I know that it is a switching power supply based class A/B amp. It looks like a real killer product but there is very little practical info. on it. Stuff like what it cost new and what a fair price for one now is totally missing.
    Any info besides the readily available operating instructions would be appreciated.

    old but

    1st gen switchers that few were sold and JBL dumped them super cheap in '97 and dropped the whole line.

    not recommended for any use these days. Some groups bought a pile of them and tweaked the supplies but they are still prone to failure and the newer stuff is 10X the power/weight anyways.

    look at the new crown ma's - 12000 watts in a chassis that's less weight than the 6670(A)
