HiFi 6DJ8 6922 6N11 Tube Buffer Preamplifier Board Based on X10-D Vacuum Tube

Product Details:

Based on X10-D preamplifier circuit. The output adopts deep negative feedback, reaching a very high index, and the distortion rate is reduced to an astonishing degree. Positive and negative DC power supply. The cathode resistance and capacitance of the second-stage amplifier tube are cancelled, eliminating the negative influence caused by the cathode resistance and capacitance. Sier-plated ceramic tube socket.

Power supply descrtion:

Dual 12V~30V DC power supply! It is recommended to use a regulated power supply, such as LM317.337. The filament needs 12~12.6V power supply. This power supply can use an independent 12V, or you can directly connect the 12V filament to the 12V of the main power supply. In this case, the main power supply must be dual 12V power supply instead of dual 15 or 18V power supply, because in this case the filament The voltage will increase or even be damaged! Of course, the filament can also be powered independently.

Specifications:

Distortion: 0.008% (10Hz～100KHz) Frequency response: 10Hz～100KHz (±0.2db) Output impedance: 200 s Output signal 1: 1 buffer Tube uses 6DJ8 or 6922 or 6N11 size: 100*100MM

NOTE:

Choosing [DIY All Kit] requires the buyer to solder and aemble it by himself. Choosing [Bare ] to not include any components.
