I just bought three of them off eBay in non working condition. The seller didn't say what was wrong with them, and I'm not sure if he even tested them. I plugged one it for about 10 min and the output of one set of speaker terminals is 35 mv and the other is right around 1 mv. Would I be safe to hook it up to a preamp and a set of speakers?
They all look the same inside, it looks like someone was doing some mods.
