DIY mini T2 Build Thread

I like the idea about to-252.

First draft… 

 …have to think about this.

XLR ground pin to signal ground on PCB.

Correct me if I am wrong.

The Ground Pin(Pin1) has been connected to the XLR socket shell by default by the manufacturer in some cases.

This way, the ground pin should be left unconnected to avoid a looping ground.

In this case, the loop may be like this: XLR(Pin 3)-> AMP signal ground - > L bracket - > chassis -> XLR(Pin 3).

I just realised the L-bracket is isolated to the signal ground, so it should be fine.🤐

I assumed the amp chassis ground wires are connected to the PSU chassis somewhere, and the amp signal grounds are merged with the XLR ground, and then connected to the PSU power supply ground somewhere.

the neutrik jacks i used in the diy t2 are actually 4 wires. the connector shell is a seperate wire. i put in a jumper to chassis ground for that wire.
