Hi All, I'm new. This is my first post. I'm building a PA system (a first for me). Found a Peavey CS800 online (Merry Go Round). Purchased it and had it shipped to my house. I figured I'd do a basic test, power it up and turn it on. I did that, and sparks flew out the front of the CS800. I contacted the seller. He said, "Power amplifiers should never be powered up without a load (speaker) attached. That is why you saw the fireworks show when you flipped the switch".
So I'm just looking for a sanity check. Is that right? Power up CS800 without speakers attached, and you can expect to see fireworks?
Thanks in advance.

CS800 Power with no load
Re: CS800 Power with no load
Some very old style amps required a load before turning on, but that hasn't been true for decades, so I would be highly suspect. What is the full model number of it? Is it the kind with the "back porch" where "crossover cans" can be plugged in?
Re: CS800 Power with no load
All Peavey CS800 amps can be powered on with no speakers plugged in or no load. Many Tube Amps liked to have a load on them. The person who sold the amp to you either doesn't know what he is talking about or is telling you a lie because he sold you a damaged amp. Any chance it was damaged in shipping? You did nothing wrong with powering up the amp with no speakers plugged in.Woofer123 wrote: ↑Sun Jan 24, 2021 10:57 amHi All, I'm new. This is my first post.
