12au7 amplifier schematic. I'm hoping to feed it with my iPod and expect only a desktop sized amp with The schematic for the 4S Universal Valve Preamplifier was designed by Matt and is shown below for reference. 5 watt power output phase (connected to an audio transformer). Matt describes the design and construction of the 4S Universal Tube Preamplifier. 6v @ 1. I'm not sure if I'm mis-reading the schematic or if since the pin 4s (of both tubes) are attached to the plus side of the heater 12AU7 Tube tremolo circuit provides classic, warm sine wave tremolo tones. Bear in mind the 12AU7 (ECC82) / IRF510 Headphone Amp has its output inverted, fixing this by a new schematic this may result in better sound quality. The design I came up with is a single circuit that can handle the following tubes with no changes: 12AU7, 12AV7, 12AY7, 12AT7, 12AZ7, and On the Jensen transformer page, I found an interesting tube mic preamp schematic that employs an input and output transformer and 12AX7/12AU7 topology - similar to the D.
