Vox AD120VT on the bench with a LOUD hum. Turns out it’s spitting 45VDC onto the speakers, which is usually a sign of a blown output transistor. I opened it up and noticed this:

Had my three-year-old daughter on the amp workbench today. She had a great time helping out. Got her doing the simpler side of thing: unscrewing the back panel, pulling out the speaker cable, replacing filter caps, etc.

Hope you taught her how to discharge them filter caps first - you cant walk before you crawl you know.

Tonight I hooked up a switch to go between cathode bias and fixed bias.

Feels good!
