Description
One Siemens Germany 4CX250B Transmitting Vacuum Tube
These are almost impossible to find, especially European made tubes. These were made by Siemens in Germany. These tubes were sold to us as brand new, NOS NIB. They are in the original box with the original packing. Date codes are 076.
Some of them have light discoloration around the bases and heat sinks which may suggest they have been used. Since there is no way to test these tubes outside of installing them in a transmitter, we really don't know. So we are selling them as used but in working condition. If your tube arrives and it is unusable we will accept a return, no questions asked and will pay for the return shipping.
