Low DCR Single Ended Tube Audio amplifiers

DT667 has been posting on various audio forums for years referencing Dennis Fraker of Serious Stereo aka Tube Wrangler and Jeffery D. Medwin aka drlowmu.

Those guys have inspired DT667 to experiment with single-ended tube audio amplifier circuits featuring LOW DCR power supply filters and other design concepts they have developed over the years.  They have also influenced DT667 to listen to Altec theater speakers and adapt them to domestic listening environments.

DT667 considers Fraker and Medwin to be "HIFI" SE tube amplifier builders.   Guys who are willing to commit the time and $$$ to compete at a "world class" level.

Dennis Fraker has dominated listening rooms since 2004 at RMAF with his SE DC 2A3 amplifiers and GPA 604 III duplex speakers. 

Jeffery D. Medwin has been working on his own groundbreaking SE DC 6005 tube amplifier designs while mentoring a new generation of SE tube amp builders from across the globe.

DT667 is far more of a "tube amplifier experimenter" than an audiophile or HIFI tube amp builder.

"Circuits get screwed down on a breadboard. "  - comments DT667

DT667 does not go to audio trade shows and it has been years since he has been over to someone's home to hear their audio system.

DT667 doubts that much will change in the C-19 era.

"Not sure where we are all going with the hobby or life in general. "  

Time will tell.
