I have a few TKD potentiometers available. All of them are dual linear taper 50K resistance made with conductive plastic. These are all new and unused. Pricing is firm at $50 for the 2CP-2500 (25mm size) type and $20 for the 2CP-601 (16mm size) type.http://www.tkd-corp.com/products/att/pdf/cp600as-e.pdf http://www.tkd-corp.com/products/att/pdf/cp2500as-e.pdf Shipping in the USA is $5 via USPS and outside of the US will be rated based upon location.
