Tubes for Vox AC15
Era: 1958–presentPower: 15 W
The Vox AC15 is the AC30's smaller sibling and arguably the more recordable of the two — 15 W of EL84 break-up plus the same chime. The original EF86 channel produces the most singular Vox sound; later models swapped to 12AX7 for production reasons.
Complete tube line-up
Every socket in the AC15, with stock tubes, direct-swap alternatives, and rolling notes. Tube names link to dedicated specification pages.
Important: bias before you swap
Power tube swaps almost always require rebiasing — running a new quartet of EL84 cold or hot will shorten tube life dramatically and can damage the output transformer. See the biasing guide and the troubleshooting guide before rolling tubes.
