6N3 Tube Hifi Buffer Audio Pre-amplifier Amp Board with Transformer

Description：
This gallbladder has made some changes in the famous circuit, which not only widens the frequency response, but also has better low-frequency extensibility. The sound is round and exquisite, and can be heard without tire. It is equipped with domestic 6n3 or new 6h3n vacuum tube from Russia and the Soviet Union, high-quality capacitor, 1% metal film resistance and high-quality small sealed volume special potentiometer. The materials are reasonable and in place. PCB adopts red solder resist layer, which is noble and generous. PCB adheres to the design style of reasonable wiring, beautiful and tidy.

6n3 tubes have long been discontinued. The supporting 6n3 tubes are new or disassembled products. All tubes have been tested and we deliver them randomly.

Specification：
Magnification: About 4 times
Board size: 80mmx103mm (excluding potentiometer and RCA base projection)
Transformer size: 55mmx60mm, 50mm high (distance between fixed holes: 72mm)

Reminder:
We can provide two kinds of transformers with primary voltage of 110V or 220V. Please explain if you need 110V. Otherwise, we will send 220V transformer by default.

The transformer must be connected to the right line, and the wrong connection will damage the transformer (the appearance may not be visible)
