OK I ran curves on the highest and lowest prs. All stock falls somewhere within these extremes in the current shipment of premium globes:
highest: 55ma/-50V/250V
lowest: 43ma/-50V/250VI'm running the 55ma ones in my own amps at this moment.
BTW, of the several thousand 2A3, 300B, 45, KT88, 6550 and EL34 power tubes curve traced from US/China/E. Europe countries, the average spread is about + or - 25%. Of course the higher gain tubes have more variation, lower gain, less.
