I have a pc5032 power amp board that I have some questions about some of the semiconductors have been replaced and i am wondering if these are suitable substitutions.
I am going to list the questionable components by what the schematic says should be in there and what i have.

Q1 se4002/2222a
Q4 38735/nte128
Q7 2N3567/nte128
Q8 2N3638/nte159
Q9 se4002/2223a
Q11 2N3567/nte128
Q13 se4002/2222a

I am aware that some of these semiconductors can be replaced with nte123 but all I have is nte123ap's will that be acceptable?

I posted in a previous thread in the repair forum that I have about 20 volts + and - going to the preamp and was wondering if any of these mismatches could be contributing to my voltage issues.

Thanks
Nate
