In the RangersAudio.com room had a pair of Quad loudspeakers,
Wolcott model The Presence P220-M monoblock tube amplifiers, Shaki Hallograph (see our review of these by

Dan Wright of ModWright SWL 9.0 four tube version (prototype) reference pre-amplifier is pure "Class A" with four 5687 triodes. Choke power supply FRED and Schottky rectifiers, regulated heater supply, and constant current source plate supply are just a taste of the action my friends. There is also a smaller, two tube version (see photo below).
