Default ppi pc 6600.2 - Help Please

Hi, I am new to the group and I am looking for some help. I have a PPI PC 6600.2 amp that I am in the process of trying to fix. I need to find out the order of the transister numbers 2N6488 & 2N6491. They are on the front gain, rear gain and sub gain of the amp. Someone put all 2N6488 transisters in there and I am trying to get it fixed.

If the speaker output terminals are connected to the emitter resistors, the center leg of the 6488s connect to the positive rail. The center leg of the 6491s connect to the negative rail.
