I'm new to the world of amps using "three legged fuses" or solid state devices (I'm currently into tubes). But I recently ran across an interesting amp design on the 'net at:

Anyone care to enlighten me if this might be a good project to tackle?
Thanks to all,
Steve

If you are interested, i recomend you read AN-211 (from analog devices) (The Alexander Current-Feedback Audio Power Amplifier).
I don't recommend any current-feedback amps. Have lots experience with them, and we did not care for the results. Ditto for using them as I/V stages.

Now that I've looked at the schematic.....
I'll second Nelson's opinion. Only thing different than 99% of the other amps out there is the input stage. Oh.......the feedback goes into a low impedance point. Not what I think of when someone mentions "current-feedback". Yeah, I know Harry.......you do.

Take a look at the sch. from Velleman kits.
Something wird about the feedback loop around IC7. Looks like current and voltage feedback combination.
What you think?
