Hello,

The title says it all. I'm almost done building my Crack. Resistance checks are all greens, except for the black RCA center pin and the ground tab that both read OL. So I'm guessing there's a missing/bad solder somewhere, but I'm not sure where to check.

Any idea what could be wrong ?

Thank you !

Edit : I found the faulty joint for ground tabs. It was on the lower pin of the potentiometer, closer to the 9 pin socket.
Edit 2 : The fix above also appears to have fixed the other issue. Double checking resistance and moving on to voltage test !
Edit 3 : Voltages are all good, the amp is working ! Listening to it with my DT1990 and HD6XX and I can't hear anything wrong. Guess I'm good to go ! I'll listen to it for the rest of the week and install the speedball in the weekend  :)
