    I have three, 4CX250B Eimac tubes. One may be unused (left). The other two had "new" written on tape on their boxes (but that tape dried out and came off). However, they are both tarnished, which could mean that they have been heat cycled. I really don't know their history other than what the guy at the swap meet told me(!), and I have no way of testing them. Here's a link to their data sheet:

    I'm asking $80.00 shipped for all three, Payment by PayPal.

    Please contact me by email at: ( mycall at arrl dot net), or by a PM here. Thanks. 73, Jim KO5V

    I just can't verify their history. They may be new...
