important hint
1. The power depends on the power supply and speaker impedance, THD=1%, RL = 8Ω, VS = ±25V, Po=25W;
2. LM1875 has been discontinued, using the old stock white genuine 1875; 6J1 tube has also been discontinued, using stock products, the brand may be shipped randomly from brands such as Shanghai, Beijing, and Shuguang;
3. Please pay attention to monitor the temperature of the heat sink during use, if necessary, it is recommended to use a fan to assist heat dissipation;
4. The design size is for reference only, and there is a deviation from the actual product, please refer to the actual product.

It is recommended to use dual 18V transformers for the power amplifier board, if dual 12V is used
Transformer, please short the jumper point on the back of the circuit board.
