Western Electric: Vintage Transistors / Diodes Collection

This site contains my collection of vintage transistors and diodes, most of them included with their original package or sleeves. The devices are produced in the late fifties and early sixties except the MOSFET's from Sony they where made in 1975. Enjoy the collectables and click on the picture links for more details. Suggestions regarding these transistors are welcome. I'm always looking for new semiconductor items to complete my collection, so if you would like to sell or exchange something, please contact me, jan@transparentsound.com.
