Elliott P72 Rev A - Non-inverted Gainclone - LM1875
This is the first Gainclone I built, so I decided I'd take the easy route and build an established project with a PCB, bill of materials and comprehensive assembly instructions.

Initially, I had the two feedback reversed. This caused a gain of less than 1 which is well below the recommended minium gain of 10. The sound quality was OK but the volume available was rather low.
