I ordered a quad (top 10%) of the "Global" labeled KT88-D from Grant Fidelity - eagerly awaiting arrival. Alas, "express shipping" is S-L-O-W....
That said, GF would not reply to my question of differences between the tubes labeled "Global" vs the plain brown printed labels.
Don, do you have any insight into the differences (if any) of the 2 types of labeling by Linlai factory?
Thanks!
