No audio right ear [resolved]

[Opal]

I just finish building my Crack and all the voltage test pass. Power it up and everything seem to works... untill i put my headphones on my head. No sound for my right ear.... I resolder the red RCA Jack made sure everything is welded and wired properly like 4 times. I did notice that the 12AU7 Tube did glow both half but one half was way dimmer thant the other side.

Here is the voltage test result
1 86.6
2 176.8
3 0.0
4 176.6
5 81.6
6 0.0
7 110.6
8 0.0
9 110.3
10 0.0

The 12AU7 should be just fine since your DC voltages are correct.  Could you show the terminal side of the volume pot?

There are some 1/4 to 1/8" adapters that don't quite work properly in the Crack's headphone jack.  If you're using one, I'd try a different set of headphones to be sure it isn't something simple like that.

You sir are awsome....that was the issue. Cheers to you and your love one. Now time to enjoy it

The fun thing is that the headphone jack is a Neutrik jack, and I've seen a Neutrik 1/4" to 1/8" adapter not work when plugged into it, go figure!
