With fairchild transistors and the TL072, I did run into some low end frequency distortion. It was corrected with an op amp change. I didn't really look into why it was happening as the new op amp made the problem vanish, but I thought I would put it out there for posterity.
@@qddk9545 eh.... I don't agree. That's antiquated thinking. While I DO favor discrete designs, opamps in well designed and implemented applications will surprise you. I built this amp and it runs against some of the best discrete designs I've built and heard.
@@qddk9545 I know this is a couple of years later, but you should realize that you can swap out the op amps for discrete packages that fit in the same socket (SParkos Labs, orange, and Burson).

Very interesting and helpful presentation. Thanks Wayne.
This was great thank you
Hey Wayne, how about releasing the design as Open Source? For those of us new to builds, why not also include the motherboard design?
It is out there....
Many thanks
Great content. Unfornitaly the video quality wasn't good.
Did he say OP-AMPs ?? I´m out of here.
Why?
@@asplmn Because op-amps are not HiFi.
