Fair.

MuuuHahahahahahahahah

OK,
all you folks out there!

Lets work on it that Nelson´s really challenged to top.

As he states that fairness is not necessary (which I personally
like. Fairness is something for Golfcourses and often not even
there

) we do teamwork and he is alone.

This looks like it's going to be fun to watch. If I wasn't so far away I'd offer to help. If you can think of anything that you may need ASK!!!!

Nelson needs a little competition.

Does anybody mind having some kind of dc-servo in the circuit?

When I was younger and did my first homegrown preamp
with audiophile approach I cap-coupled the output (first
quality PP caps).
I later tweaked that pre to dc-servo instead of those caps
and was fascinated by the quantumjump in soundquality.

Is it allowed to mix up a Pass design with opamp servo circuitry?

Uli

Promise: the board will be at least 11" long

mwmkravchenko · 28th November 2003, 02:22 AM

Realising that a servo will require active devices ( trannies if you follow the rest of your circuit) and that a cap is simpler. Why not make it possible for the difference to be tried. Both. Let the user find out the differences.

Yeah as the pcb will be a universal one, I will implement both versions.

Interesting, not often we see any of your masterpieces.
