many opamps are "self-centering"


to the p/s rails, and not a problem. I don't know about Rane, just mentioned it as "a no-no" w/ the adcom input circuit. They put a cap into the input of some later amps(5235), to prevent the level adjustment pots from buggering the input bias as well.
I had looked hard into buying the AC-23, but balked at the opamp count, and the need to convert an unbalanced source to balanced for the input.

Speakers are DONE! JBL 4648a-8 bass bins, 511 Altec/909 drivers, and jbl 2404H tweets.
Amps are in the rack! 200wpc for bass, 100wpc for mid, and 60wpc for the highs.

Just waiting for "the MIB" to park his Viagro m/c and get back to work on the electronic crossover:) Sam
