On a side note, though Noel Webster of Muscle Shoals lied through his teeth to me about the working condition of the board when he sold it to me, and even with all the money I'm putting into it, I don't know if I'll ever get the board to full functionality, I have to say that working on the restoration of the board with my tech has been a remarkably educational experience! The different op-amp and cap choices and ("Stock, Nashville, or LA style") configurations has seen the channels of the board produce remarkably different sounds, all of which I think have musical applications. With the BB OPA-134 chips the board sounded like a more exciting version of a Neotek Elite, with the 5534's the board sounds very "warm" and "musical" for rock music but I'd like to get a little more clarity. Next week we're trying out the BB OPA-604 chips, and then hopefully the week after that the Sage Red and Blue discrete ICs will arrive, which are very expensive but supposedly sound amazing. I can't afford to do the board entirely with Sage so I was thinking put the Sage chips on the mic and line inputs, then find an op-amp choice that will complete the channel modules without imposing too much of their own sonic character.
