  • Amplifier R-105: AMI E40
  • Amplifier R-111: AMI E80, E120
  • Amplifier R-144: F40, G40
  • Amplifier R-145: G80, G120, G200, H, I, J, and possibly K


  • Resistance: 35 KOhm
  • Resistance tolerance: +/-10%
  • Volume: 2 Watt
  • Electrical Taper: Logarithmic
  • Shaft Style: Slotted
  • Shaft diameter: ~ 6,35 mm (1/4")
  • Length of shaft: ~ 22,3 mm (7/8")
  • Bushing thread: ~ 9,5 mm (3/8")

Nachdem das original Potentiometer beim Verstellen der Lautstärke schon ziemlich gekracht hat, bin ich froh einen Ersatz gefunden zu haben.
