A modification from bride of ZEN and Power Follower 99c.....
Can anybody tell me does it work?
I want to take output cap off.
I add DC-servo.
Thanks!😀

An externally hosted image should be here but it was not working when we last tested it.
I tried both links, but neither worked for me.

What is a Power Follower 99c? Whose design is it?

Andrea Ciuffoli´s powerfollower is a very fine circiut. I have build two of them.
I believe Your circiut will work, but I am pretty shure that it wount beat the original design. Take a look, and read his text carefully over and over again, it is more sufisticated than the most, specially his consideration on the relation between the singlerailed powersupply, the outpucap and the grounding, all this is gone in Your scematic.

The power followers were the first class A things that I had built, but they were too low of power for my Dynaudios. Went on to build a pair of Aleph 2's which are almost finished now. The power follower does sound good though.....

My fault, it was my firewall´s cookiecontrole wich denied the use of cookies this way.
But that should not be nessesary to go to this extreme use of cookies, show your picture elswhere.

I haven't analyzed it carefully, but it looks like the
designer is smart enough, and it will probably work.

OPA637 in a DC servo?
Did you get them as samples and don't know what to do with them? 🙂
I'd try something way cheaper since low THD and high speed is not what you need here...

Hi
I won't use OPA637 on test ckt.
Maybe OP27/OPA132 or something much cheaper....
Thanks
