Marantz 1030: quick question about replacing drivers

[dubwoofer]

I have a marantz 1030 with one channel that distorts when playing above medium volume. Someone before me had worked on it and used incorrect parts in a few places, including the drivers. I'm replacing them with 2N5415 and 2N3439 and would like to find out if they need to be matched by hFE.

Thanks
