Transmitting Tubes

We carry a full line of Transmitting tubes from around the world. Each of our tubes are TESTED IN AN ALPHA AMPLIFIER.

This is why we can warranty our tubes. When you purchase a matched set of tubes from RF Concepts, they have actually been matched! The tube(s) in a new Alpha amplifier have been installed, tested, burned in, and tested again. Those tubes are warranted. If you replace those tubes with others during the warranty period, RF Concepts is not responsible for any damage caused by those tubes and the damage will not be covered under warranty.

Please contact us directly if you have questions about this policy.
