6J1 with exellent linear and working status when plate voltage as low as 50V, adopt AC 12V low voltage power supply, through voltage boosting up to +/- 28V power supply, to extend tube lifespan and improve SNR
Positive and negative DC power supply, can full use components of transistor; components easy to find, and low cost
Board designed volume controlled potentiometer, power switch, power input interface, audio input and output, convenient to use
Installed orange LED in digital tube's bottom; It will flash yellow light in working. |
