My G-6000 produces a characteristic "vintage" smell when turned on. Is this common or a sign of a failing component? I have had it for 3 years and am currently recapping. So far, I have replaced the filter caps, and those on the driver board and deoxited all pots and push buttons. Seems to be all original and little dust inside. Overall, was pretty clean when acquired with a little muddy, non-punchy bass. Any experienced guess as to what component (and where) may be causing this? Or if this is a common characteristic smell for the G-series?
Once reconditioned with total glue removal included the smell almost completely disappears. I would describe the smell as Citrussy, Sickly Sweet, and a bit musty, and tends to be more noticeable when the unit has been powered on for ½ hour or more.
