You got it right. Just use a file but be careful not to go too far as that will let the leads flop around in the sockets.. Sneak up gradually on a clean but snug fit. Use a very fine file that doesn't remove too much material on a single stroke.

I should add that the sockets can take only so much manipulation when installed on the board. A preferred method is to use a spare socket off board and fit it over the lead as you adjust the size.

I had better luck using needle nose pliers (on each lead close to the end) rather than fingers for the final insertion on the build. I don't even try to do a swap or rotation without those, good lighting and some sort of magnification.

Hi Jac,

as Bob already pointed out using a file you can do it.

But for bigger leads (like C13 ones) PCB mount faston tabs (Mouser 571-63756-1) are a better choice than sockets:

I powered up both channels and something is wrong and i cant understand what. Voltage across 3886 and 318 are ok but relay does not click. I dont have CC on output but the voltage acros relay coil is 12 volt. Infact before R14 ihave 24v but after i have almost 12v the same like on relay coil.
R14 is a bit warm.

Is the LED coming on? And are both amps doing the exact same thing?

Yes the error is the sameon both channels. The leds are ON but normally a should have 24v across D4 (diode paraleled with relay coil) but i have only 12v.
I will try to disconect R14 and see if without protection circuit connected i can measure 24v.

LE. Seems that DC protection is hungry. Disconnected R14 and i have 23v before and after. I will take a closer look to the DC protection circuit.

The relay needs about 15 volts to activate. Reduce the 470 Ohm resistor to 220 Ohms and try it again.

If and when you have the time, some 90 degree photos of both top and bottom would be helpful.

O.T. Got a reply from Uriah and he is feeling much better and is making good progress in his situation. Let's keep him in our thoughts and prayers.

Found the problem! Someone from Mouser put 0.82k resistors instead of 220k resistors.
Now my relays clicks !

OT Good for Uriah !
