Super rare!! As expected, Western's US Army military amplifier “Beach Master,” which is equipped with a cooling function, is an amplifier for use in outdoor loudspeakers, and boasts a non-standard 150W output, and when I actually played it with a JBL 4345 at the store, I was able to enjoy it with a very strong sound and just as powerful sound. ※ There is a strong fan and vents inside, so be sure to close the lid when using. If you open it and use it, it may cause a malfunction. Also, the gain is very large (49 dB), and there is slight white noise when silent, but this is the specification. You can hardly tell while playing music. There is no difference in sound pressure between the left and right, and the operation is stable. Please only buy if you understand. The exterior has scratches and stains. Serial 1846, 1440 (Sasaki Shota)
