I was working on a customer's Marantz 140 today, and I wanted to replace the differntial input pair with some 2SC2240 transistors. I got to looking at what I had, and they were very different from each other.
The one on the right is a genuine Toshiba part from Mouser. The one on the left is an apparent fake, I'm not sure where it came from. It's pretty sad when the Chinese are counterfeiting 20 cent transistors.
