Default vintage sansui transistors

hi, i was given a rather tired looking sansui solidstate 2000amp/reciever and its really really old. now,when it was in one piece,it had a really violent sound (in a good way) but it is now devided into two pieces. the only bits which i have kept are the pre and power stages,rather,the most improtant parts of each stage. now,the power section has four huge transistors mounted onto a heatsink,the tranies have " sooken " or "sonken" written on them and then under this is written 2sd202 then 98. what does all this mean,they look really bulky and are capable of pushing some big current.

2SD202 = NPN 80V 6A 50W you should be able to replace it with BD245C, 2N5633, 2SC2681 or 2SD718 according to my list..
