I think I saw you request a service manual on another thread.
I don't see one available in the usual places.
Its worth going out there and buying one.
OR take it to a service tech if there are any good vintage ones near you.

I suspect an output transistor blew out, but it may be a driver transistor, an emitter resistor, a bias trim pot, a bias diode, a bridge rectifier diode.....

I've never seen a Nikko NR-1415 so I have no idea how they are built.
So I am just guessing.

We'll at least need the manual to be able to even try to help.

You will also need a dim bulb tester.
You will need a Digital Multi-meter (DMM).
Probably a good soldering station, solder sucker or wick, solder.

You will need to be able to read a schematic, understand and follow directions if you continue here. You may need to provide photos so we can help.
