I know the goal here is to clone the krell but I am curious ; would it work to split R15 and put an integrator's output in the middle, dynalo style ? Requires to modify the servo and get rid of C10, C18 and C19 ...
When I built my dynalo, the transistor and diodes were too poorly matched for the servo to function. After swapping leds (and taking advices from Justin) it kicked in to reduce the offset to less than 1mV.
I remember amb told us about it a while ago, glad to see it is finally here. With Super Symmetry, is it possible to wire two output jacks in order to use it single ended or is it simply not an option ?
I was sure someone was going to comment in this way. I have the choice of how much DIY the amp is going to be.
I could always try to do the amp like in the original article, on a breadboard, but I would prefer to have already designed and printed boards.
