K4 Supply Company sells new and used, hard to find model trains and parts and also stocks a selection of vintage electronic parts, books and manuals.
Our used model train parts are refurbished in house and are guaranteed to perform as good as new. We specialize in parts for Athearn, Mantua, and Rivarossi trains. Additionally, we sell new model train detail parts, decals and kits. Many of our new items are sourced from liquidations and old inventories, thus we often have available hard to find items that haven't been made in years.
On the electronics side of things, we currently have a sizable inventory of books and original repair manuals pertaining to electronic musical instruments by Yamaha, Roland Boss, Fender and more. Additionally, we have a varying selection of vintage and newer electronic components such as transformers, connectors, relays, vacuum tubes, etc.
