 PEAVEY DECA 700 The first time I saw one of these amps, I wanted one so bad it hurt. Damn shame I was 14 and it was around $700. Years later, here comes eBay so now I have come across a few of them, in various states of operation. The first amp I get my hands on had a blown "b" channel. 
 These parts are on the output side of the channel power amp board. As parts are difficult to find, I was using this amp for a single sub channel. I had found another that was listed as broken, and when I opened it, this is what I found.  Yeah, I didn't see anything wrong with it either. I looked all over it, and when I tried to power it up, it refused. It had a wonderful life for the last 15 years as the mains in some guy's home theatre system. It quit working one day so he bought a new one. Turns out it had a blown fuse. So, for the next 2 years, it became the mains amp in my home theater/pa system. One night, my youngest boy and I were hot and heavy in the guitars when we heard a odd noise comming from the B channel. I stopped playing and started looking, but he kept playing. A few seconds later, there was this ominous pop and the B channel cut out. I immediatly looked at the amp, which had started pouring smoke out of the top right. It took me a few seconds to get to the amp, as we were on the other side of the room, but I knew it was too late to save it. The magic smoke had already escaped. A few days later, I finally got it aired out enough to take apart (it still smelled, tho), and this is what i saw. 
 As you can see, these pictures were taken a year or so after it happened. The missing parts went to the B channel on the other amp, which became my mains amp. This single channel amp is now my test amp. It can be seen on my Kicker Enclosure Project. It still stinks. |
