    Anyone have the Paradigm Active 20 Schematics?

    Hello, so I found a pair of Paradigm Active 20s off the curb and thought that they would be some nice speakers to add to my collection. Once I got home, and plugged them in, I was immediately greeted with static. Once I quickly pulled the plug and removed the amplifier, I was immediately greeted...

    Marantz Model 26 Pops Fuse

    I recently started working on a fuse blowing Marantz model 26 for a friend. I have looked for at the usual causes but the only problems I can find are the filter cap, which started leaking after I pulled it, and the 0.5ohm resistors connected to the output transistors read open line. I have...

    Pioneer SX-1050 Output Transistor Help

    Hi everyone, about 6 months ago I had 4 speakers hooked up to my 1050 and I made the great mistake of dropping the needle too hard on one of my Zeppelin records. The pop was quite loud and it killed my 1050 as well. It only popped the main 10A fuse on the rear and nothing else. No smoking or any...

    Marantz Model Twenty Five?

    Hey all, A few years ago, I got a Marantz Model Twenty Five off of a friend of mine when she moved out of her house. It was owned by their grandparents, who used to sell audio gear in the 70s.

    Marantz 4270 Help...

    Alright, so I've got a Marantz 4270 with a bad channel, spitting out DC and throwing it into protection mode. Only one of the output transistors was shot, I believe it was the one that handles the negative swing. Otherwise, all the semiconductors on the board and otherwise are testing OK. I can...
