Hello everyone! I need your help.
I built the Crack + Speedball for first time, but I just built the Crack first. However, I got some problem with this Crack.
1. The LED to the center terminal of the nine pin socket A and A3 did not light up.
2. It is so noise if I put the 6.3 mm on the way down of the headphone jack. If I move a bit up, so no noise.
3. When I turn music on and the 6.3 mm is on the way down of the headphone jack, only right headphone channel works, but if I move a bit up, then 2 channels work well.
I have checked and rebuilt 3 times so careful, but couldn't find the mistake. I don't have multimeter for safety check, but I believe everything I did was right. Can anyone help me to fix this problem? and what can I do? Thank you so much.

Your first step should be to get a multimeter. Second step would be to remove the Speedball and return it to stock form. Once you have the stock Crack working, then install the Speedball. Much easier to troubleshoot the stock circuit.

Building a high voltage kit like this is a joy if You just follow the manual, build it stock first with all resistance and voltage checks and then eventually mods like the speedball. It is, however, potentially lethal if done carelessly.
The multimeter is not optional.
This forum is great and will provide all the help You need,
but You'll have to reverse engineer Your kit back to the resistance check if You want more than educated guessing
