211 SE - Mono Amplifier

TECHNICAL HIGHLIGHTS

  • Single ended triode operation from input to output

  • Pure Class A

  • Zero feedback, neither local nor global

  • Zero solid state parts in audio circuits

  • Unregulated and overspecified supplies

  • Separate transformers for each task (three in total per side)

  • Short signal path - from RCA to pot - 2 inches of silver wire, same  from pot to first tube,  same from the first to the second tube and a hop across one capacitor to main tube without additional wiring

  • Power tube bias current is monitored on analog needle meter

  • No need for triode matching as the bias is set manually

  • There is a possibility to compensate aging drift on power tubes

  • Pre-heating operation mode for tube (and for electricity saving)

  • Pots can be bypassed completely by toggle switch for the “power amp” operation mode
