Features
Using FU19 parallel Class A amplifier circuit driven by 6n2,Tube amplifier output 4w+4w
output 4w+4w power amplifier to promote the speaker requires an impedance of 8 ohm Two-way divider speaker, sensitivity above 90db, 6.5 inches or more, headphones 19-600 ohm (about 1w)
Vacuum Tube Headphone Amplifier Use all AC filaments to light up, use 102DB headphones to test the sound, no humming noise can be heard,
Vacuum tube amplifier is as quiet as it turns on.
1 . Use all AC filaments to light up, use 102DB headphones to test the sound, no humming noise can be heard
The tube amplifier is as quiet as it turns on.
