Has anyone seen anything around using gainclone's with K1000's? I was just poking around on natl's site and came across this:
http://www.national.com/pf/LM/LM4700.html

Higher slew rate than the lm3875 used in most gainclones, and lower output current. The minimum supply voltage is 18v. Has anyone seen any projects using this opamp?

I use a battery powered LM3875 for my k1000 amp. It sounds good to me. Hopefully, in a month or so, I will have a Dynahi to compare it to. Don't know about the 4700, have you searched the chip amp section at diyaudio?

SR 1300 V/us, bandwidth 100 MHz, dist 0.000021%, 700 mA out, why don't you test TPA6120?
