Hi
I would like to build a small preamp based around the OPA134 or AD797 with a 4 transistor follower discrete buffer. I've hunted around but can't find anything.
Can anyone point me in the right direction please. The voltage rails are +/- 15v but I can go higher on the output buffer as I have an extra winding on the transformer I have (+/- 24vac with a center tap).
I would like a Class-A discrete zero-feedback buffer as I have seen one somewhere.....but where?
thanks for the help
Rob
