Hifi Fever 6j1 Electron Tube Front Pushing Digital Amplifier Board Amp DIY Kit

Loose Parts DIY Hifi Fever 6j1 Electron Tube Front Pushing Lm1875t Small Amplifier Tube Digital Amplifier Board Amp DIY Kit

Introduction:
Supply voltage: the default double AC 18v/ current 3A, 60W above (maximum voltage can not exceed double AC 19V), also can not be less than 18V, otherwise, the electronic tube point is not bright, the sound distortion. If you need to use AC 12V, you need to modify the filament down voltage resistance to 2.2 , then the output of the amplifier will be slightly lower
Amp / front output: of about 0.8 times (AMP function can be used, can promote the high sensitivity of the headset, thrust, amp output can also be connected to the output of the current level of functionality, promote electronic tube amplifier, has a taste.)
Lm1875t output: typical 20W (maximum 30W)
Speaker impedance: 4 -8
Total harmonic distortion: less than 0.04%
Signal to noise ratio: 105dB
Frequency response: 14Hz-100kHz (by RC high pass circuit is considered as the maximum range 3.29Hz-482.29kHz)

Package Included:
1 x Digital Amplifier Board
