I've found a circuit... ETI-1977- projects book 1&2...page 34.
No worries then, those two projects books wouldn't happen to have the schematic for the ETI 183 Valve Distortion Unit in it by any chance, would it?, it's a circuit that uses a single 12AX7 Valve which is powered by a 15V/1A transformer.
