Modulus-686: 380W (4Ω); 220W (8Ω) Balanced Composite Power Amp with extremely low THD

These were the terminals I was able to find on Mauser they say they'll take up the 14 gauge but I can't even get a piece of 14 gauge in there successfully and I'm realizing if I take these out and solder I'm not sure if I'll get a 14 gauge wire in the soldering hole on the board. The soldering post of these terminals are 7 mm does anyone know where I could find a bigger terminal block that's suitable for what I'm trying to do that could at least take up to a number 12 so it could accommodate my 14 gauge for sure.

Yeah. Those terminals are fairy small. The ones I use on the Power-86 and -686 take up to AWG 10 if I recall correctly.

You'll get the best connection with a crimp terminal as long as you can get a good and gas-tight crimp. The latter bit is often overlooked by DIYers who crimp using those stamped metal crimp tools that come for free when you buy a set of spade terminals.

Connectors are pretty reliable these days. I use the same JST connectors as Hypex in the Modulus-686. I'm not worried about failure. I do not offer the Modulus-686 without the connectors. The connectors lock in place in the PCB so they will be really difficult to remove and you run the risk of damaging the board by removing the connectors.

Power supply complete no magic smoke no fireworks. everything looks good on the oscilloscope nice clean output. Now I got to save up for the amp modules which I'm extremely excited about. still haven't even purchased the speakers or finish the room the amp is going in so it's going to be a minute probably mid late summer.
