Pictures of the backsides of the boards....

Post by Dragon1 »

Hi,
Anybody take backside board pictures of they"re #124 builds?
Looking for jumper picks and under board wiring. Some of the board pictures are hard to see through, espeicially the "FET" board.
Thank you, Brian

You can get a good idea from these layouts. Reverse engineer and apply to whatever layout you are using . https://ampgarage.com/forum/viewtopic.p ... t=Bias+fet

All three eyelets at the top left on the FET board are ground, all tied together. The output eyelet only goes to the middle of the pot, the wiper.
