Crack voltage issues / LEDs not lit

[Paul Birkeland]

Alright, you can actually listen to the amp like that.

The non-glowing LED probably got broken or melted in the build, and will need to be replaced.  You can e-mail replacementparts(aht)bottlehead(doht)com

Paul--  Thanks for all your help!  I'll request a replacement LED.

I just plugged in my HD650s and the Crack sounds pretty good!  Is it going to sound any different when I remove the jumper and replace the LED?

[Paul Birkeland]

Probably not. In hypothetical terms, a shared cathode connection can lead to crosstalk, but the dynamic impedance of that particular red led is so low that this isn't realistically a problem.

Thanks, that doesn't surprise me, given how good it sounds in it's current state.

Hey guys

Thought I would comment here as I have a similar issue. I have manage to completely melt one of the LED lights. will it still work without this or should I just order a replacement ?

Replacing it is best even if the voltages still read correct. If the voltages are not correct you must replace it for sure. You can order some replacements at [email protected].
