Note: This is a tube preamplifier diy kits. The kits does not contain 4 magnifying tubes and it needs to be soldered by yourself.
 
 
1. Adopting Hetianmao circuit design, the driving load capacity is stronger than the Marantz 7 circuit. Mid-frequency sweet, analytical and high-low frequency response is also better for Marantz 7.
 
2. The PCB board is double-sided gold-plated and has high quality.
 
3. The circuit filament adopts full DC design, and the high voltage also has voltage regulation filter and low noise. (Note: the input impedance of the tube is high, the input must be shielded, and the chassis is also grounded, so the noise is very low.)
 
4. Support 50W ring transformer, need 3 sets of voltage (AC 240V-0, 6V-0, 12V-0.)
