Before above, after below.
The buttons were all encrusted, unlevel and stiff. Isopropyl alcohol, diluted Dawn dishsoap & WD-40 contact cleaner did wonders.

Decided to clean the Technics sa-450 amp instead. Buttons are a mess, inside is full of dust. The sound from the test I ran, is superb (for my flat). See collage pic for before #technics #technicssa450 #technicsamp #vintageamp #amplifier #hifi #vintagehifi
