PPI PCX1250 NEED help on transistor outputs

skinnman33 · 9th November 2011, 03:41 PM

I have a PPI PCX1250 and need to know where the TIP35c and TIP36c
transistors go. Bought it for $20 off E-bay, and it came without the outputs. Anyway If someone can tell me if It's setup like all TIP35c's on one side and all TIP36c's on the other side, which side do they go on. I figured you good people on here would know faster than me trying to track it down. Thanks.

I don't have any information on this amp but you can determine where the NPN and PNP outputs go using your meter.

On each side, does the solder pad for the 3rd leg of each of the output transistors read ~0 ohms to each other and to one of the speaker terminals?

Check and confirm for both sides.

If so, the TIP35s will have their center leg/pad connected to (~0 ohms) the positive terminal of the rail capacitors. The rest are TIP36s.
