4SUTea - Super Simple Single Stage (4S) Tube preamp

4SUTea is another Super Simple Single Stage (4S) Tube preamp that I have built. This one features single board construction with PS and amplifier together and no PCB. All housed in a Twinings timber Tea Box: Bitumanised aluminum foil controls enclosure resonance and Russian paper in oil caps link the modulated HT to the real world. Silver solder is used throughout. Heavy duty high grade gold plated RCAs grace the back and all is powered by a 24V 1A plug pack. There are two switchable inputs, Alps blue velvet pot and black chromed solid brass knob.

See the project page 4S Universal Preamp for 12A?7 Valves.
