Sound loss has been minimized by reducing power loss through B-voltage drive after mounting two choke transformers (66mm).


An analogue meter reads sound output and checks current flow of output vacuum tube. A user can adjust the current flow to an optimal condition by referring an analogue meter.


A digital meter measures up to 0.0001V of voltage and checks Hum voltage The voltage is adjusted to the optimal level. Therefore, it is safe even in high-performance speakers. It guarantees clean and dynamic sound that you can never experience in other products.
