Default Replacemet NEC power transistor

Hello,
On my audio amplifier one channel doesn't work. Pair of power TO3 NEC
transistors were damaged (NEC 2SD188A and a NEC 2SB545A).
I can buy these transistors but model 2SD188 is without "A" and 2SB545
is with "A". I try to find some information or data sheet of those
transistors but without any results.
Can I use 2SD188 without "A" and 2SB545 with "A" on the left channel and
2SD188A and 2SB545A on the right channel? Is it OK?
Any help is greatly appreciated!
Best regards!
