For Sale is the fantastic top of the line Sophia 6SN7 tubes. I was using these tubes in my ModWright Sony 5400 ES cd player that is now sold. For those not familiar with the Sophia Electric name these tubes are hand selected out of the TJ tubes at the factory which also makes brands such as Full Music, only the best tubes carry the Sophia Name. Then Sophia grades them A-C. A being the best of the best. The tubes for sale are Graded A and are a matched pair. They have approximately 300 hours on them. I am also including a pair of Herbies Tube Dampers with this sale. My selling price includes PP fees and shipping. USA sales only.
