New Parallel version:

At present, there have been direct-inverted dual-amplifiers. The output tube has changed from the original pair to two pairs. The internal resistance is reduced, the output current is larger, and the low-frequency control force is better. The core circuit board is as follows:advantage:

1. More power;
2. The amplifier output has a smaller internal resistance;
3. The low frequency power is better!
