TUBES - 3CX400U7 Tubes w/4 sockets *Special*

**
I have 4 each 3CX400U7 tubes with 4 sockets. Three of the sockets definitely fit the tubes but the fourth one may need to be modified slightly. The date codes on the tubes are 1 - 0026, 1 - 003?, 1 - 0034, 1 - 0039, 1 - 0108, and 3 - 0113. They all came out of working equipment I have been told. I have no way to test them but I did do continuity checks between all elements and all readings were infinity. All tubes had continuity on the filaments. They look like they are in nice shape with clear lettering on the tubes.
**
I am asking $39 for each tube and $79 for the each of the three blue sockets and $20 for the fourth socket. You must buy at least three tubes to get one of the blue sockets. Buy all of the tubes and sockets for the special price of $399, "as is", no returns, with free shipping and Paypal.
**
Offers entertained.
