Details:

These tubes are 12 years old with only about 150 hours on them. Free shipping in the lower 48. These are the xls version, which is 15 larger, runs at 100ma and is a direct 300b replacement. They are a factory matched nos pair in the original box.

They were rotated in and out of my Cary 300b amps that I just sold. At less than 1/2 the cost of new. Here is a rare opportunity to own a wonderful, hand made set of 300b tubes.
