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
