Mesa Boogie STR-415 & STR-416 Power Tube Set, Phillips/Sylvania 6L6 GC, EL34, 6CA7, Mark III, IIC+

Here is a set of Mesa STR-415 6L6 and STR-416 6CA7/EL34 power tubes removed from a vintage Boogie power amp. Recently tested using an old Hickok machine and they were all in the green/good range, but well into the bottom half. I usually wouldn't sell tubes with this little life left in them, but they are so hard to come across I figured I would make them available to anyone looking for a set. These old Sylvania tubes are supposed to be very heavy duty, but I have no idea how much usable life they really have left in them. These are not NOS tubes. Used!

Will be shipped using Reverb shipping. Being these are delicate vintage tubes I cannot guarantee anything other than they will be carefully packed before shipping. I will fully insure the package using Reverb Protection.
