Yesterday I've find in my stock about 10 tubes I got 7 years ago
they are surely NOS, selled without a box (if I remember correctly I payed it really on the cheap)
They are surely triode/pentode tubes but on it there isn't a standard Tube Label, only a number
My memory is I got it as ecl8* or pcl8* tubes but I don't remember if they are the 82 or 84 or 86 models, may be pcl86 but not sure at all :BangHead: :BangHead: :BangHead:
What can I do to identify it correctly ? (I've an emission tube tester to perform measures, the other one that can measure gm need some manutention)
Many Thanks
