Marantz Split Knob Outer Knob for 22xx and 23xx Series

Product Description

Elevate your vintage Marantz restoration with our premium outer knob for split knob tone controls, proudly designed and manufactured in the USA. This listing is for the outer knob only, part of the split knob assembly used to independently adjust left and right channel tone settings (e.g., bass, treble) on Marantz 22xx and 23xx series receivers with split tone control knobs.

Crafted from high-quality aluminum with a durable clearcoat finish, this outer knob features the authentic Marantz swirl pattern for a solid, premium feel. Available in Gen1 and Gen2 variations to match your receiver’s era, with Gen3 coming soon. Pair with our inner knob (sold separately) or check our upcoming split knob set to complete your tone control assembly. Combine with our Marantz faceplates for a restoration that looks better than new.

Important Compatibility Note: This outer knob is designed for the split knob tone controls of Marantz 22xx and 23xx series receivers with split tone control knobs (e.g., 2240, 2250, 2270, 2325). It is not compatible with models using single knob designs or other series. Verify your receiver’s tone control style before ordering.

Mounting Details: The outer knob mounts securely using a D-shaft with the same clip spring mechanism as the original Marantz design, ensuring a precise fit and easy installation.

Marantz Split Knob Outer Knob Identification Guide (22xx and 23xx Series)

To select the correct outer knob, compare your existing split knob’s outer component to the descriptions below. Marantz used different knob styles across production runs, so visual inspection is key.

  • Common Models: Early to mid-1970s 22xx series, such as 2240, 2250, 2270.

  • Best For: Restoring the authentic look of early Marantz receivers.

• Gen2 Outer Knob

  • Appearance: Includes a black indicator line on the face for enhanced visibility of settings.

  • Common Models: Mid-1970s 22xx and 23xx series, such as 2240B, 2250B, 2270B, 2325.
