6N3 push 6P1 single-ended amplifier production ----- 6N3 + 6P1 Power Amplifier

6N3 push 6P1 single-terminal courage production, 6N3 + 6P1 Power Amplifier Keywords: 6N3 push 6P1 single-terminal player production 6N3 push 6P1 single-ended production Use two 6P1 power tubes to do three-dimensional A-class output, output power is between 2-3W. Since the 6P1 tube works in pure A, the sound is sweet, the actual unreasonable volume is comparable to the transistor amplifier of about 15W. With high sensitivity speakers, it is the main voice and light music, and its tone is not absolutely high-grade audio! Be Using 6N3 single-stage amplification without large ring feedback Actual production: Be This production uses 45W radio cattle, full-wave rectification, 150uf + 340 Eurof filter, outputs small single-ended cow with dawn and easy! The overall quality is very high, and if you are interested, you can make it, the sound will not let you down! The power transformer is the three sets of output (Double 230, 6.3, 6.3) disassembled on the red light. Output transformers I use dawn old easy cow! You can also change it with a small power transformer (5-10W). Specific as follows: 6P1 (6P14 / 6P15, etc.) small power gallbladder output impedance is around 5K ohms, and the load speaker impedance has 4/8 ohm. The initial coil of the output transformer is This calculates RS = 4one when q = 31, which is consistent with a transformer of 220 / 6.3 V. RS = 8oum n = 22.3, consistent with the 220 / 9V transformer. This voltage ratio can be utilized, and the power transformer of 10 W is used. Since the output cattle has direct current! The core is easy to magnetic saturation. Therefore, the power transformer is modified to output the cattle's core to open, and the method of change the original interleaved sheet is the E-piece and the I slice, and the two-part core junction pad one layer 0.2mm thick film is separated. The cartridge must be close, otherwise it will affect the sound quality. Test is also very satisfied:
