    Thank you @pmillet, I will check that out. I'm so curious to hear this amp!

    I am at the very end stage of my build! I just need to finish wiring it up. I've got a few last questions though that I want to make sure I get right...

    I've decided to install a stereo jack off board and want to make sure I wire this up right. What numbers correspond to the Ring, Tip, and Sleeve of the jack? The PCB has six soldering points, but I assume that I only have to use 3 of them. Can anyone tell me which ones correspond to the Ring Tip and Sleeve?

    I've also decided to install the 24v DC jack off the PCB. Can someone also confirm which numbers correspond to the Ring Tip and Sleeve of the back of the installing DC jack?

    Lastly, do I need this third wire connected to the On/Off toggle switch? Or can I just leave it off?

    My thanks in advance.

    On the headphone jack: 2 = tip, 4 = ring, 6 = sleeve.

    On the power jack: 3 = tip = positive, 1 = sleeve = negative.

    On the power switch: You only need the two pins farthest from the PCB edge
    (green and white wires in the pic).
