Description: Alps Catalog # RK27112A0-S25-C0-A503 This is the GENUINE ALPs Blue Velvet pot used for volume control in the very best headphone amplifiers. The 50K impedance is ideal for headphone amplifiers, with 100K being too noisy and 10K allowing bass loss with some source connections. The 50K impedance is the ideal impedance for headphone amplifiers The problem with 50K impedance Alps RK27 pots was that Alps never stocked or supplied 50K RK27 pots, except for custom manufacturing runs. The last time I purchased these was almost 10 years ago, directly from Alps through a US-based electronics wholesaler. I had to purchase 200 (!) pots, minimum. (See the pic for a typical box of 100!) These are the few that I have left over after retiring and shutting down the regular Beezar Audio online store. They are the very same stereo volume control that myself, Tangent, and AMB have sold to the DIY headphone community since about 2005. For Beezar Audio, these were used as the volume control for the Millett Hybrid MAX, the Millett Hybrid MiniMAX, the Millett Hybrid MOSFET-MAX, the Torpedo I, II, and III, and the T4 headphone amplifiers. I also supplied these pots for many of ECP Audio's amplifiers, including the L-2 and many of the DSHA amplifiers produced by ECP Audio. I absolutely guarantee that these ALPs Blue Velvet pots are GENUINE and are the finest volume controls - short of a several $hundred stepped attenuator - that you can purchase.
