Robert Reverse Engineer Sep 24, 2022 #3 I think that was a different (larger) project with amp / cab sim and other bells and whistles. This is just a simple headphone amplifier... a step in that direction.

Bricksnbeatles Member known well Sep 24, 2022 #4 @Robert same drill sceme as the Celsius CE-1 preamp?
Robert Reverse Engineer Sep 24, 2022 #5 Aside from the LED, yes. Although I might will relocate it in the next revision so the drill templates are 100% compatible. Also, there's no footswitch in the headphone amp. Last edited: Sep 24, 2022

Robert Reverse Engineer Sep 24, 2022 #7 Nah, the RefDes just need to be reindexed. You're looking at everything. It uses a pair of LM386 and a pair of TL072.
