Hope you can help guys.
I have this Teac D500 d/a convertor to mod.
The two output opamps are NE5534's easy enough to change.
The other four have me stumped, they measure like they are dual opamps but i can find no info on them so i can change to something better, the no. is AD42712.
Two of them could be dc servos, and the other two maybe I/V stages.
And all the trimpots, two maybe initial setting for the dc servos, as there is no coupling caps all the way to the output, but the other six, could they be for dac trimming?
Any help will be appreciated.
Cheers George
