Kenwood KA-7100 cleaning and repair.

Heloo. I have amplifier kenwood KA-7100 and it is is currently in very poor condition. But it is working.
So I decided to clean that amplifier and to make som rapairs on my kenwood.
But i it is very difficult, because i dont have all parts and it is difficult to buy parts in bosnia.
I need for my kenwood 2 output transistors 2SD427 and 2SB557. And i also need 4 conds, it is 4 big one ELNA 50V 6800 microF.
So can any budy tell me how to make repairs and cleaning job, and whre i can buy thease parts.
Thank you very much for answers.

I'm using MJ15016 (15) on outputs when the originals are blown. Easy to find but a lot of fakes around.
PM me if you need links where to get them.
