EL34 el34b 10W Single-Ended Cl A Tube Amplifier power amplifer diy kit board-kit no tube

EL34 single-ended cla A tube amplifier only kits requires you to solder, without 3 piece Tube

This circuit design uses 12AX7 (or higher-end ECC83) as the voltage amplifier and EL34B as a single-ended Cla A output. The rectifier section does not use low-efficiency tube rectification, but uses Phil's rectifier transistor and field effect tube electronic filtering . The music baground is very quiet and the extension is excellent.

The electronic components of the circuit are simple and the welding is simple. But if you want to make a complete power amplifier yourself, you need transformers, audio transformers and other acceories. Requires you to have electronic technology skills. If you are not an audiophile and do not have the ability to do it, please do not buy this board. Thank you
