Valv-e-tizer 1.1/1.3/1.4/1.5 – DIY

[wpdm_file id=45] [wpdm_file id=26] [wpdm_file id=25] [wpdm_file id=4] Did you ever want to build a real tube pedal but you have been embarassed by the disadvantages: high, lethal voltage free wiring all the irritating schematics then this is for you. Valv-e-tizer is a project running on 9V pedal power builds like any other effect circuit […]


Versatile 1-valve circuit: Gain, Tone, Volume-controls Voltage multiplier (60V/80V based on 9/12V input) Variable cathode resistor pots can run the second stage as cathode-follower easy to tweak from clean to distorted The Valv-e-tizer project will continously be put forward to improve layout of the board and functionality. Several ideas to optimize the circuit and to […]
