[sdiy] OTA subs & schemos WAS CA3080s purchased - now available in small er lots

[Tim Parkhurst]

So here are the questions I have about this whole 3080/OTA thing:

1) What sort of adjustments or changes would you need to make to sub a 13600
or 13700 into a 3080 circuit?

2) The 13600 is closest to the 3080, and the 13700 is a little more like the
3280... right?

3) What adjustments or changes would you need to make to sub a 13700 into a
3280 circuit?

4) Where are some schematics for transistor/IC based 'roll your own' OTAs?
