I make a photo copy original circuit board then print in a photo paper then I used an electric iron to transfer the printed circuit to the pcb board. I have a short video how to make a circuit board czcams.com/video/N9jyB9sRyGk/video.html
I don't have schematic diagram I copy the actual circuit board. You can usually find this kind of preamp in a turntables like Sony, Aiwa, Pioneer, Denon and especially audio-technica.
Superb work sounds decent .
Thanks a lot!
good work👍🙏
Thank you! Cheers!
the one you built has so much more depth
👍👍👍
This circuit is great for its single rail PSU. The IC is not so easy to find tho. Very elegant video thanks for making
Welcome
Woody, where did you get the blank board and how did you make the traces? I'd like a video just on that process.
