大家好！我是个音响爱好者，多年来一直沉迷于复古音响设备。我拥有一些经典设备，比如索尼 KA3ES 卡带机、索尼 F555ESX 功放、山水 AU-D707 功放和一台爱华 HS-J303 随身听。 最近，我把随身听拿去修理，它又能工作并发出声音了，我真的很高兴。 然而，在维修过程中出现了一个新问题，我一直没能解决。这就是我来这里的原因——希望找到解决方案，并期待与其他爱好者一起学习和交流。
Welcome to the forum! It sounds like you have some nice equipment, I love those big Sansui's, I have the AU-919 but need to find the matching tuner which is getting more expensive every year. Good luck with your repairs! Hello everyone! I'm an audiophile who has been obsessed with vintage audio equipment for many years. I own some classic equipment, such as a Sony KA3ES cassette player, a Sony F555ESX amplifier, a Sanshui AU-D707 amplifier, and an Aiwa HS-J303 Walkman. Recently, I took my Walkman in for repairs, and I'm really happy that it works and sounds again. However, a new problem arose during the repair process that I haven't been able to solve. That's why I'm here - hoping to find a solution, and looking forward to learning and communicating with other enthusiasts.
