I hear you Tom. It does seem fairly silly for what should be a simple set of transistors.
I think doubt is always going to be a problem with obsolete parts, regardless of the number of counterfeits out there. My over-whelming instinct is to just use a current production part and be done with it.
BTW, this being Head-Fi and all, I fully expected a full range of contradictory opinions. 
Yes, well I hear you. I don't blame you a bit for trying to confirm that what you've purchased is genuine. Head-Fi is the perfect place to ask the question, too. It's just that from my perspective, those transistors are contaminated with so much counterfeit-urban-legend that the investment is simply not worth it. It's sort of like chasing the Holy Grail - only to find out that many other goblets taste just as good with far less hassle.
