12AX7 Tube Preamp with 5AR4 Tube Power Supply

Twinings Tea Box preamp with external valve rec. PS

Another Tea Box valve preamp but this time with a valve rec. remote PS. The rectifier valve is a 5AR4. The iron consists of a Hammond power transformer and 10H choke. Golden Dragon tubes are used in the 12AX7 Tube Preamp . The preamp uses silver hook-up wire, Alps Blue Velvet attenuator, brass cones and 4oz brass knob. Jupiter hand made beeswax caps are used in the amp modules and silver solder throughout. The sound stage has gained greater dimension and detail has improved over my SS preamp.
