EL34 Vacuum Tube Amplifier Single-ended Class A HiFi Stereo Amp 10W x2 DIY Kit Item Detail: New: 100% New and High Quality Model: EL34+ECC83 single-ended Class A Stereo amplifier Kit 10W*2 PCB size: 170x99mm Output power: Class A 10Wx2 Transformer voltage: 230VX1 (can range from 200V to 250V, greater than or equal to 300MA) 6.3VX1 (2A current) Tips: This is DIY KIT, you need to solder it by yourself. and the price not contain three of tubes,pls Note. Latest Version, HIFI circuit Design, Most cost-effective, Amazing Effect, Strongly recommended! ! ! Features: 1. This circuit uses 12X7 (or higher level ECC83) as the voltage amplification, EL34B as a single-ended class A output 2. The rectifier uses Philip's rectifier tube plus field tube electronic filter, the background is quiet, the extension is very good 3. Using DALE resistors, Philips high-voltage capacitors. 4. Cathode capacitors use Panasonic brand 5. Coupling capacitance: VIS BC high voltage capacitors 6. EL35 can be replaced by 6P3P, ECC88 can be replaced by 12X7, but 6P3P power is smaller, if you want more power, you can use KT88, cathode resistance adjustment 7. The alignment is very optimized, and the input is shielded 8. only need to weld well, do not hit the cooling holes, the whole machine is free of debugging, wiring is very small, only need to lead out the output transformer line, it's easy to assemble Parameters: PCB size: 170x99mm Transformer voltage: 230VX1 (can range from 200V to 250V, greater than or equal to 300MA) 6.3VX1 (2A current) Output power: Class A 10Wx2 (You can choose other tubes according to your request, Small power: 6P3P*2+12X7, Or for large power you can choose KT88,remember to adjust the cathode resistor) Some customers have reported that the resistance is not big enough. There is no need to worry about it. All the precision calculations, such as EL34 cathode resistance current is 50MA, the power consumption is only 0,85W on 330 ohms. We are equipped with 3W imported resistance. Absolute capacity is abundant. Attention: * Tubes and output transformers are Not Included. * BC capacitor 100U is discontinued to supply, the product picture shows BC-100U-400V will be replaced by 100U-400V, both are the same quality * The tube is a Class A single-ended output, the tube temperature and the cathode resistance temperature are a little high, which is normal phenomenon. Packing list: 1 x PCB Board 3 x Philips BC220U - 400V 2 x Philips BC22U - 400V 4 x Panasonic 220UF 2 x VIS MKT 0.22UF 2 x Terminal 2 bite 1 set x U.S. DALE resistance Tube seat 1 x G40N150D transistor (Second hand,Used,but original ,quality is guranteed) 4 x Philips 2A rectifier transistor Tips: Please allow 0.1- 0.5cm error due to manual measurement.
