Arcam Delta 290 Int. Amp. 的 Input Select 問題

本人有一台Arcam Delta 290 Int. Amp. 的 Input Select 有 「接觸不良」問題，約一年前拿了去樂聞修理。
但因沒有新零件更換，當時只是做了清潔，但半年後問題再出現！

** 樂聞曾建議bypass個Input select：放棄多個輸入，只接單一輸入！
請問各位CHing，有冇較長遠的解決方案介紹？

或者用另一款selector.

要配合你部機先得, 有無現有Selector 的相?

Attached please find the photo of the selector, the cover was soldered onto the PCB and cannot be removed without taking out the PCB. The brand is ALPS.
