I'm scratching my head by seeing the input selector knob woobling a little bit of my Marantz PM5005. :sad:
Is this common on every amp. The volume knob feels very solid and couldn't wobble by a little push from left or right side but when do the same with the "input selector"...
Just thought of sharing my Potentiometer Knob build using solid aluminum.
The knobs are CNC machined to get decent precision and finish.
After machining, the knobs are done with the following anodized finish.
Flange diameter: 38mm
Top diameter: 28mm...
