3. ReisongA10 EL34 Hi-Fi Audio Stereo Tube Amplifier Single-end Class – A Amp
- With an English Operation Manual，If you need a circuit diagram, please contact us by email, thank you!
- Manual welding, preferred audiophiles, the output transformer switch to the higher end of the 76 * 40 output transformer.
- When low-frequency dynamic playback is good, control and strong, it is more powerful.
- Tube: EL34 × 2，6N2J × 2，5Z4PJ × 1
- Warm reminder: You should take about 30-100h time to operate the amp.RUN-IN to the amp gives it’s best and stable sound.So during the first 100h use time the sound maybe is not the best,you can also use your own run-in method.
