Up for sale here is this mixed lot of 84 5-watt IRC black enameled 1% precision resistors, from the 1960s and Made in USA. These are new old stock--brand new, never used. These are guaranteed to work great for you, and will probably test within 1-3% of their marked ratings. There are a lot of different ones here, and there will be multiples of most of the values. Please see my pictures for details.
US shipping and handling is $12, and international is $28. If you have any questions, please ask.
I have more resistors and other vintage electronics listed--feel free to take a look!
