Tips: it is Kits.not include the Tubes.Thanks

Two channel, one 6N2 tube pushing two 6P1 tubes. There is no rectification or filtering part on this board, and high voltage requires DC power supply
Compact and mini design, only 7cm x 10cm, all three tube filaments are independent and not wired on the board

【1】 Which electronic tubes can be replaced with,
6P1 can only be directly replaced with the Soviet 6n1n, but with the addition of a conversion seat, it can replace 6A
Q5 or 6P6P/6V6
6N2 can be replaced with 12AX7/12AT7/12AU7 (filament needs to be changed to 12)
6V power supply)
Alternatively, it can be replaced with ECC82/ECC82/ECC81 (starting with E is not required)
Change the filament voltage, etc

【2】 How to install a transformer
Output transformer 5k
Power supply AC high voltage single 250V or double 250V, rectified and filtered to high voltage on the board
280V DC, at least 2 sets or more 3V filament voltage

Resistance capacitance list:
18 resistors in total
5W/270 ohm: 2 pieces
2W/100 ohm: 4 pieces
2W/4.7 ohm: 2 pieces
1W/470K: 4 pieces
1W/200 ohm: 2 pieces
1W/1.5K: 2 pieces
1W/7K: 2 pieces

10 capacitors in total
300V/10UF: 2 pieces
450V/4.7UF: 2 pieces
35V/220UF: 2 pieces
50V/47UF: 2 pieces
Coupling capacitors: 2

6N2 and 6P1 are both audio specific electronic tubes, the effect is beyond doubt, and the sound quality will not be poor

Packaging:
1 piece (Kits.not include the Tubes)
