Replacing 2SK 215/2SJ78
 

My friend has a power amplifier with 2SK215/2SJ78 mosfets in the driver stage. He is not getting original devices so he needs to change it. The output is 2SC5200/2SA1943 pair. I don't hv circuit. Has anybody done some replacement like this?

There is no substitute for these devices. However, they are still in production. Hitachi has separated their discrete semiconductors to Renesas:

You should be able to purchase these for a few dollars each.
