Details:

Most listing items I have collected came from estate sales and/or garage and yard over the years. Please place items in cart. These items are used and due to the age in most cases vintage stuff. Smooth increase/decrease in 25 turns.

Almost all specs are from research, but without manuals I cannot guarantee or verify these correct numbers. If I find something is non-working or broken, will list as such. This is caused by lighting, monitor, or camera settings. Bourns 3250L-1-503, 50k ohms 1w, 25-TURN, trimmer potentiometer/vintage/nos.

Tested as seen in photos.: new old stock. I do basic simple tests to see if an item works. Will pack and ship to ensure that it arrives in good condition.

Real deal Neal.
