Pioneer SA-708 Transistor Replacements!

I am working on a Pioneer SA-708 and would like to know if I can replace the 2SC2238/2SA968 transistors with ON Semi's MJE15032G/MJE15033G? The manual also states that these 4 transistors should be hfe matched. (unless that was someone else s notes)

I found that the left channel has had most of its transistors replaced with RCA SK series, as well as the 4 output transistors on the heatsink.

The Left Channel had 0mV bias reading.
The Right Channel had 150+ mV bias reading.

Also the 2SA949 which sets the bias for the outputs was changed on the Left Channel (the channel with a zero bias reading)

Here is a list of transistors I have in stock, hoping most of these will work:
MJE15032G/MJE15033G
KSC1845FTA
KSA992FBU
KSA1013YBU
KSC2383YTA
KSA1220AYS
KSC2690AYS

Here are all the transistors I want to change:
2SA726S
2SC2229
2SA949
2SA968
2SC2238

I know I'm getting off topic here. Biggest concern is whether I can replace 2SC2238/2SA968 transistors with ON Semi's MJE15032G/MJE15033G.
