I understand tri-phase more now, thanks!

I'm using the Smartstim's Midistim design, which I haven't built yet so I'm not sure how it all works. I've read the guide and have a vague understanding. But I'm not sure what you mean by output jack or wiring harness.

If you mean the 3.5mm to 2RCA cable, I think I'll get something like this.

If you mean the resistor + terminal blocks (I assume that's where electrodes are plugged in?) I'll be getting both from Allied Electronics from the p/n listed in the Allied Electronics part list at the bottom.

Here is where I'm getting my parts unless something's wrong with it. I'm listing all in case you meant something else or want to take a look at the specs.

Both these from Amazon: Amplifier and PSU

These 5 from Allied: Resistor, Transformer, Terminal Block, BLK Patch Cord, RED Patch Cord

The rest like plate and cable ties, I'll have to find in a store (I'm not familiar with any diy but I'll get it eventually).

I also read your reply in that other thread about the quality of transformers. It seems the Allied one is the same as the Zoro one in the smartstim downloaded parts list. The quality should be good then as long as nothing goes wrong.

edit: I need to find a new source for the 1 or 2 terminal blocks, Allied require a minimum of 100... I heard the terminal blocks don't need to be exact so I can get away with a variation. I found this terminal block and it might work.
