These are five helipots acquired at a surplus equipment product. They actually may be new but I'm considering them used. Four are Borg Equipment Division model 205 micropot potentiometers, Total Res. 5,000, Lin. Tol. 1% 1L. The other one is a Beckman Instrument helipot model A RIK L. 10. There are no knobs or dials available with them. Sold as is. Shipping weight about 3 lbs. Buyer pays for shipping. Please contact for exact cost.
