For Sale NOS 4CX100A/JAN 8168: Up for sale is an Eimac 4CX1000A/Jan 8168. As far as I know this tube has never been used and the tarnish on the tube is from sitting unsealed for years. It was sent to Richardson Electronics for testing and meets all parameters for a new tube. It will come with a copy of the test data sheet and the original packaging, which is a bit shopworn.
