Good value for money

Solid construction for the price. The scale plate is a nice touch that helps with precise adjustments in my lab experiments.

Authentic look and feel

Matches the original parts from the 70s perfectly. The black finish is matte and non-reflective, which is exactly what I wanted for my collection.

Perfect fit for my vintage radio repair

The 6mm hole fits snugly on the potentiometer shaft. The bakelite feels sturdy and the scale plate is clearly printed. Exactly what I needed for my restoration project.

Good quality, slightly tight fit

Great looking knob with a classic aesthetic. It was a bit tight getting onto the shaft initially, but once seated, it feels very secure. The copper core adds nice weight.

Excellent for DIY projects

I used these for a custom amplifier build. The scale markings are precise and easy to read. Highly recommend for anyone building their own audio gear.

Reliable replacement part

We order these regularly for repairs on older test equipment. They hold up well over time and the bakelite does not crack easily under normal use.

5 FAQ

Q: Is the scale plate removable?

A: The scale plate is integrated into the design of the knob cap and is not intended to be removed.

Q: Will this fit a potentiometer with a 6.35mm shaft?

A: No, this knob is specifically designed for a 6mm inner hole. It may be too loose for a 6.35mm (1/4 inch) shaft.

Q: Does this come in different colors?

A: Currently, this specific model (MF-A series) is only available in black.

Q: Can this withstand high temperatures near vacuum tubes?

A: Bakelite is heat resistant, but we recommend maintaining a safe distance from direct heat sources like vacuum tubes to ensure longevity.

Q: What is the outer diameter of the knob?

A: The outer diameter is approximately 25mm, suitable for standard panel mounting configurations.
