Haha, yes. I just sold a load of old (rescued) Crown devices to a guy here. C4751, C6492 as well as some rescued MJ15015/16 and MJ15022/23. The guy said that he prefered using old, used transistors to the new stuff that risked being fake.

Sad but true, I pay more for used transistors than for new ones for that very reason. I'm not sure that the crown ones were great in period but certainly 22/23/24/25s are always in my wish list

sorry, .. but at this point it is worth changing the configuration of the amplifiers with the new 2SJ162 2SK1058 and modifying the PCBs with side connection

Can you still get (real) J162/K1058's? I have used them and they were fine, but I think no longer fabricated.

BUT - replaced by the ECX10N/P20 range which is available. But again, not cheap.
