Hum from Technics ST-K50

[filmis]

There's a low hum from my Technics ST-K50, it sounds like the transformer. Sound quality unaffected but the hum can be annoying when the system is off or quiet. Wondering if there's anything I can do about this - I opened it up but there doesn't appear to be anything identifiably wrong with it, caps look ok, etc.

Unplug it!

Or you can unplug it, open it up (corefull, the big caps still have juice in them), unscrew the transformer and remount it on rubber bushings. This should help. You can also go crazy and order some dampeners specifically for 50Hz.

I thought about it but it's soldered to the board...

I'm having this problem too.
