EIMAC YU158/ Ham Radio Medical MRI TUBE Made in U. This tube will put out full power of 1500 watts and more with 35 watts of drive. I put a new tube in my Amplifier and it put out the same power as this YU158 on 15 meters! Still a lot of life left in this tube and I would still be using it but I bought a new tube and I don’t need a spare. Don’t use my Amplifier much.. it’s all in the antenna!! The tube will not be DOA.. I have had this tube since Nov of last year and finished my build in Jan of this year.. Tube has had little use.. And it does work great! ….
