Replacement Knob Philips Audio 34mm

This is a replacement knob for vintage Philips audio equipment from the late 70s early 80s. If the outer aluminum shell can be reused only the inner part is required. The nob fits for 6mm D-shape shaft. A cylindrical spring with ID 8,5mm and height 6.5mm is used for clamping the knob to the shaft. This spring can be replaced by a coil of wire with 2-4 windings.
