Title: Smoking + no sound output
Post by: swuuggs on February 07, 2014, 11:44:26 AM
Just got done building my crack, and don't have any sound being outputted from the amp.

Also, the unit gets incredibly hot, and smokes slightly.

It passed all the ohm and voltage tests, as far as I know.

Any ideas what the problem could be?

Ok, Smoking is bad!

Post your resistance readings that are +/- 15% out of spec.  I'm willing to bet that there are some that are wrong.

If not, did you install the Speedball in the initial build?

No speedball.

Here are my ohm readings. I understand they are quite abnormal.

I'm new to this, so it's probably an issue of a grossly mis-wired unit.

Terminal:      Ohm reading (k):

1 - 0
2 - 0
3 - 0
4 - 0
5 - 0

6 - 2.465
7 - 0
8 - 0
9 - 0
10 - 2.486

12 - 0
13 - 0
14 - 0
20 - 0
22 - 0

b3 - 0
b6 - 0

Warning: this is the ugliest wiring job you have ever seen. Also, all of the wiring ports are fucked because I painted the wrong side of the metal, so all the components are installed on the wrong side.

I would buy a new kit without the wood base and start over.

There are so many safety issues with what you've done here that I would implore you to not plug it in.

All your resistances are 0, so it failed those tests.

I can tell that all your voltages will be incredibly close to 0 as well. 

I'm going to lock this thread, as we cannot offer support on something that isn't a Crack  (it deviates too far from the manual).
