    I am relatively new to fixing audio equipment but I will try to be as descriptive as possible. I purchased a Pioneer RT-707 from Kijiji for only $100. The owner states that that amplifier has been put in water (not by choice) and it shows through lots of rust. The owner has also replaced ~90% of...

    Need help repairing Yamaha A-560 amplifier

    Recently I picked up a "fully working" Yamaha A-560 amp for cheap and it has one small problem - it isn't fully working (gasp)... Sound coming from the left channel is distorted. What I've found out is that both output transistors of that channel were not even connected to PCB. After checking...

    Hi there. As you can see on the video, the back of the tonearm rotates freely. In that way he can't hold a weight. What to do? (A piece of paper is just for demonstration. For better look at problem.) Thanx for any help.

    Pioneer Cassette Deck Buzzing

    Hey all! I am currently using a Pioneer CT-M5R cassette deck and I noticed it has a buzzing sound whenever the tape starts playing. If I lightly hit the side of the unit, the buzzing goes away for an unpredictable amount of time till it comes back. Any thoughts? Possibly grounding issue? Thanks!
