This listing is for a matched squad of Phillips made Amperex tubes that were produced in the Netherlands in the Sittard plant
All of these tubes have rX3 tube identification codes so they have matching components from the third tooling revision at that plant; and, three of these tubes have matching date codes with identical X8F date codes and the other is slightly newer with an X8K date code
So all of the tubes are from 1958, but one is from November and the others are all from The month of June
These tubes were tested on a calibrated Jackson model 103 25 is a minimum good in the average NOS tube of this type test around 38 and these tubes are testing />
So we have a strong healthy matched quad that has plenty of useful life left in it and was made for Amperex in the Netherlands
The tubes are all in aftermarket boxes and will be shipped fast safe and secure.
