It's an out of curiosity question.
There are a dozen (X)PL909 transistors in a bag that I saved after removal from my 700B. I have no intention of using them but I checked them with one of those cheap Chinese component testers. All of the transistors were identified as BJT - NPN so I assume the transistors are good but the hFE values are all quite low. The highest is 19 and the lowest is 2.
I have not found a data sheet using the number PL909. I assume they went by a different number when not privatly branded for PL. Are those low hFE numbers typical for those devices?
