Our Special Anniversary Edition of the Culture Vulture has been designed to have the same characteristics as the original, by using the same “enhancer” (or distortion) valves and the same output valve. The difference is in the Mullard M8100 input valves, replacing EF86. These give more gain with less noise, and improved frequency response. The 6AS6 “enhancer” valves are also Mullard and the output remains Philips 5963. All the valves are therefore expected to be extra reliable.
