Previously, I've removed the top cover and the aluminium front panel and knobs to access the inners of the amplifier. Over the many years of use, control knobs and front panel tend to accumulate a lot of grime and grease. To make the aluminium parts shine again, nothing better than wash the surfaces gently with hot water and neutral soap. Carefully wipe with a wet microfiber cloth, to avoid damaging the front panel lettering.
Remounting ...
... and testing.
After recapping, the sound stage has improved considerably. This little amplifier sounds really, really good.
