This unit was built as a demo DAC for our workshop listening room with B-stock chassis parts. The audio section, power supply, wiring, and all other components are brand new. The only difference between this unit and a “new” one are the minor blemishes shown in the photos.

Comes with stock RCA 12SN7/12SX7GT tubes. Tubes can be upgrade for an additional charge. See the main 6SN7 tube upgrade page
