I wonder if someone could advice me, please. Subwoofer Tannoy TS8 started to make humming noise, I took it apart and found capacitors C428 and C427 (in EMI circuit) swollen. I replaced them and it worked fine for some weeks. Now it hums again, but only when switch S200 is set to "Auto". When switched to "On", it works flawless. Anybody any clue? Thanks in advance.
