Audio Equipment

Many years ago, Surplus Sales was fortunate to be chosen as the Caretaker for Fistell Electronics' massive Inventory. No small feat as Fistell's was in business for more than 70 years!

We purchased EVERYTHING, including the pencils (literally!) and hauled it all back to Nebraska. We are STILL opening boxes of NOS vintage inventory on a weekly basis and adding these items to our Website. It is like Christmas morning every day.

Recently, we were pleased to come across a pallet of Legacy Idler Wheels, Cartridges, Replacement Parts and Needles. These items will continue to appear on our website as they are processed.

We do not repair or refurbish these items, and as such make no claims as to condition or mechanical function. The majority of the idler wheels have metal cores. If plastic, that will be noted in the item description. We have priced these items with the assumption that they will be rebuilt by the end user.

These are vintage surplus items; no warranty is implied and all sales are final. Please choose carefully and ask any questions before purchase. Please contact our customer service department if you have any questions, we are happy to assist.

Happy Shopping!
