Tubes for Fender Super Reverb

Era: 1963–1982Power: 40 W

The 4×10 blackface Super Reverb is Stevie Ray Vaughan's signature voice — the 40 W 6L6GC pair drives the four 10-inch speakers into a unique compressed mid-range that no 12-inch can replicate. Same preamp circuit as the Twin Reverb, half the power tubes, completely different feel.

Complete tube line-up

Every socket in the Super Reverb, 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 6L6GC 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.
