What to say... You will never get a chance to buy those ultra rare Sanken transistors, especially as NOS, NEVER USED!!!
One PAIR of rare Sanken transistors 2SA1068N for Sansui AU-X1!
2SA1068N Sansui used in High Speed Premium Amplifier, model AU-X1. Look at the picture taken from Sansui catalogue for AU-X1

It is the same transistor as 2SA1068 (without "N") but this 2SA1068N has non-magnetic TO3 metal case, I think made from some silver alloy...
I have very small quantity of those transistors!
I don't have 2SC2493N, but I have 2SC2493... so if you wish to buy 2SA1068N plus 2SC2493, please let me know, and I will make paypal invoice by which you will pay.
