No way I would pay $20 for one that is crazy! That said I bought 4 transistors from the same guy as you when they first hit. I might have one floating around some place still. They worked and they where cheap at the time.I bought 10 of them from the original seller Weasel years ago. The first one I installed I can remember it like it just happened, smoked as soon as I turned on the radio. I sent them all back. Maybe I just got a lemon but that put a bad taste in my mouth. But for $20.00 a piece I can buy the real thing for less.
