G'day All, With the help of list member Hsu, I just received a pair of 3-500 tubes from China. Initial observations say that they are good stuff. I've just spent a weekend on the air with them and they are doing everything expected of them really well. Thanks to Hsu for the leg work and the great packaging job. 73, Alek VK6APK http://www.qrz.com/vk6apk
