09/03/2014 Hello: I am searching for either two used and functional or N.O.S tubes: 5AR4 or 5V4. First choice is 5AR4. Second choice is 5V4. Two are needed for an amplifier restoration project. Please let me know what you have and the cost. Thanks, Ed Papson KC2QBK Email: papson_e at comcast.net Mobile: 908-309-6529
