Check the listing for details. New OnSemi Transistors for Vintage Stereo Repair All the useful ones mix & match. Condition: New. Listed at 1.00 USD. Up for sale here I have a number of different new transistors available. These are brand new and were purchased from a US distributor. All of them were made by Fairchild/Onsemi except the 2N3440 and 2N5416, which were made by Central Semiconductor. These are brand new and are guaranteed to work great for you. Some are quantity 1, some are sold in multiples. If they're in multiples it will be noted after the part number--if there is no quantity listed then the price is for 1. I use tons of these for vintage stereo repair--they're great transistors. The KSA733 and KSC945 are the "ECB" ones, with the center collector. The KSC3503 are the DS variety--I don't have the "E" ones, sorry. US shipping and handling is $5, and international is $18, no matter how many you buy. Use the "add to cart" feature if you want to buy a bunch of different ones, then you can check out once and pay for everything at one time.
