This is a really easy solution for replacing a missing knob on your classic amplifier. These knobs become brittle over time and can easily break when being moved around. The replacement knobs can be made in a few minutes from some scrap materials.

Few weekends ago I was trying to find on the net some knobs to put on a[n] old JVC amplifier [me] and my girlfriend found on the street…..The small ones (2.5cm) where reasonable cheap and easy to find but I couldn’t find any of 5cm…..So at last I decided to do them myself.
