My church's sound system amplifier died today, so I need to replace it. It's a Peavey PV 8.5C, 550watt per channel stereo power amp. I'd welcome suggestions about what to replace it with and where to go shopping. You can see the manner of the amp's demise in the photos below:- The transistor on the right has clearly disintegrated. The big capacitors in the middle are 7500microFarad 100v components. The top of the one on the top left is no longer flat like the others, but rather domed. So that's a blown capacitor, I reckon. I've got the necessary test gear to check that out, but I'd have to dismantle the amp a bit more to get at it to do that. Replacing the blown components is well within my capability. However, with those two components having failed quite dramatically, I'd expect to find a few others taken out by them and in need of replacement. Apart from that, if that set has gone, I'd wonder what the life expectancy of the others might be. I wouldn't want a failure mid-funeral when some quiet voiced relative was giving the eulogy or when the deceased's favourite piece of music was being played! So I think it's not worth bothering with a repair. The amp has been driving a pair of these:- 700W RMS Peavey HiSys 4 - Not the sort of thing you'd expect to find at the front of a church! I'm told that the church has had them and the amp for around 20 years and bought them 2nd hand back then. I think the choice of kit had something to do with the contacts / involvement some church members of the day had with bands. It'd probably be better to replace them with a set of more discrete pillar mounted speakers - but that'd require between 4 and 6 speakers and an appropriate amp. Getting that sorted out - with all the necessary agreements and permissions - will take time. So I need to get something to keep the existing system going for a while longer.
