Up for sale is a pair of 2-piece concentric aluminum knobs used in the tone controls of the Sansui 2000, 4000 and 5000 series receivers of the 70's. These may also fit other models but I am not sure, these were taken off a Sansui 5000A receiver. There are nicks and scratches but nothing major to cry home about. See attached pictures of actual knobs for sale. Local cash pick up or meet ups in nearby Starbucks in the Willow Glen area of San Jose only please. I will not sell these separately please don't ask. I also have 2 pcs. of the single volume, balance or function selector knob for these models too. $20 firm for the (2) single knobs. Thanks for looking. NO TEXT PLS.
