Excellent pair of new GE 6L6-GC "OO" getter tubes still in original boxes! 

These test very STRONG and matched in mutual conductance and current draw, settling in at about 2mA apart in current draw. Auditioned in both a p/p guitar amp and a single ended stereo. These sound awesome with wonderful vintage TONE!! Sweet clean sounding tubes with excellent detail, a pronounced mid-range and very smooth bass! 

You can't go wrong with GE 6l6gc power tubes! This set also looks very nice like the day they were made except the labels are pretty much box-worn off. 

You can safely use these in any 6L6 type amp that calls for 6L6, 6L6G, 6L6GB, 6L6GC, 7581 and KT66 tubes with no mods needed.
