Unique-Bargains 5 Single Linear 1M Ohm Rotary Potentiometers Electrician Tool

SKU CH-ZGX4-NAAZA

A pack of five single-linear 1M ohm rotary potentiometers with knurled 6 mm shafts for top-adjustment volume or tone control

  • 5-piece set simplifies stock for multiple repairs
  • 1M ohm linear taper suits audio volume controls
  • Top-adjust design allows quick calibration without desoldering
  • Knurled 6 mm shaft fits standard knobs securely
  • 7 mm mounting hole matches common panel cut-outs

Five-piece potentiometer set for audio control

This pack supplies five single linear 1M ohm rotary potentiometers intended for adjusting volume or tone in electronic musical instruments, loudspeakers and CD/DVD players. Each unit has three terminals and a Type B taper suited to standard audio circuits. The components arrive new and ready for breadboard or chassis installation.

Knurled 6 mm shafts suit common knobs

The 6 mm diameter shafts measure 15 mm in length and feature a knurled finish that accepts most off-the-shelf control knobs without modification. Top-adjustment slots allow quick calibration with a screwdriver once the potentiometer is mounted through a 7 mm panel hole.

Linear taper limits use to uniform control

The linear resistance curve provides proportional change across the full rotation, which works well for balance or tone controls but does not match the logarithmic response preferred for human-perceived volume. Builders needing audio-taper pots or values other than 1M ohm will need a different component.

Questions about this item

How often will the 6 mm knurled shaft need lubrication or replacement under normal use?

The carbon track and wiper are sealed; no routine lubrication is required and the shaft only needs replacement if physically damaged.

What electrical limit appears first when the 1M ohm linear track runs continuously at full rotation?

The 1M ohm resistance value is the fixed limit; power dissipation stays within the standard small-signal rating so the track itself sets the boundary.

Does the potentiometer generate noticeable heat or noise when left in circuit all day?

As a passive 1M ohm linear device it produces no audible noise and negligible heat during continuous low-power operation.
