notes:
1. This is a finished product, you don't need to assemble and weld by yourself.
2. Due to manual measurement, please allow an error of 1-3cm. Before you bid, make sure you dont mind.
3. The color may vary from different monitors, please understand.
4.The high-frequency power amplifier amplifier must be connected to the nominal load before powering on (the default power amplifier product in our shop is 50 ohms), this is very important!
