How do you set the op amp to the ratio of 1:2 Avedis from Brent Averal said I should set it to this... Do I need some special equipment to perform this?
(I'm guessing he's alluding to the ratio on the input trans)
I'll elaborate on Tim's response. Just set up the A12's as described in the directions, using the supplied transformers, and everything's correct for use with the SC25 opamp, the Avedis opamp, a real API opamp...
