EL34 single-ended class A stereo tube amplifier board preamplifier DIY audio amplifier board
Single-ended Class A bile amplifier is the best bile amplifier circuit for vocals, with warm and charming timbre, rich overtones, and very poisonous vocals.
This circuit uses 12X7 (or higher-end ECC83) as the voltage amplifier, the noble EL34B as the single-ended class A output, and the rectifier part does not use low-efficiency bile rectifiers. The sound of the rectifier tubes varies greatly. The Philips rectifier tube plus field tube electronic filtering is used here, so that the overall background is quiet and the extension is very good. The Sears Gold Series E0049+E0011 speakers that I use are very good.
This kit does not contain electronic tubes and output transformers, and uses imported resistors and Philips high-voltage capacitors. The cathode capacitor is a warm-sounding Panasonic. The coupling is a VIS BC high-voltage capacitor, and the tone is very good.
The output power of this kit is class A 10Wx2, don`t underestimate 10W, the general class A 5W has a very good sense of hearing and sound pressure in a small room.
