I bought a Randall Century 170 that powers up, but has no output. I've debugged stompboxes using and the audio probe in the debugging page, but before I do that I wanted to see if any of you have tips on debugging something plugged in to the wall.
I've built a bunch of gear (including a tube amp) that run on mains power, but never had to debug them...luckily only stompboxes.
Your help is appreciated.
Do you kow that the power supply works, and that the front end (preamp /tone-control) stage works?
