Balanced 768 Remote Control 6J1*4 / 6C1 Tube Preamplifier ALPS Potentiometer

The panel is made of aluminum alloy wire drawing process. The chassis is made of 1mm thin steel plate with good shielding effect and spray frosted paint process.

The capacitive coupling of metal film resistor and military Dahongpao resistor and Siemengate Millilayer cake is adopted.

4 inputs are switched by imported silver contact relay.

The input and output interfaces are gold-plated lotus seats.

The power cow is made of ring cow, imported iron core and oxygen-free copper wire winding.

Use 6J1 or 6C1 vacuum tubes *4 only for amplification.

Remote control can achieve: volume, channel switching, mute function.

The volume is made of Japanese ALPS original motor potentiometer.

Own power grid purification circuit.

There are earphones to monitor and amplify the output.

Volume knob using aluminum alloy knob.

This machine has a memory function to remember the channel state when the last shutdown.

When the system is powered on, the channel status window blinks to remind that it is preheating. When the preheating is complete, it turns to steady on and displays the current channel.

Press the mute button of the remote control, the channel status flashes, press again to restore, or press the volume plus or minus key will also resume playback.
