Gold Plated * Hi Fi Grade * DACT Type 21 Stepped Attenuator / Potentiometer 250K * D shape shaft * for upgrading Tube Amplifier

   Q : Why use Stepped Attenuator Potentiometer , not ordinary Volume control ?

  A : Nothing else to say but it is L/R absolute balanced at any volume level . Each step use 1% SMD High Quality resistors. Ordinary Volume Control will be degraded with age , temperature change (especially in Tube Amp) since ordinary one is formed by sliding circular carbon powdered tracks. It is the reason why the Hi-End equipment always uses Stepped Potentiometer.

  Q : What is the difference with GOLD Plated ?

  A : Durable and Low Contact Impedence , and the most important is the clear sound image.

  Q : Does it make "POP" sound between steps ?

  A : No, the gaps between contact is modified to "S" shape to eliminate the "POP" sound , i.e. first contact (close) before cut off (open).

  Q : Can it completely replace the ordinary Volume Control , e.g. Resistance and Size?

  A : Yes , the size of this item is standard and compact . Resistance is 250K (Audio type) , the most common value.
