    Sansui g-8000 dead left channel

    Hey all, I came across a mint Sansui G-8000 at an estate sale. Looks like the left channel is struggling. I tested the phono input and the left channel is very quiet, if I increase volume the unit immediately goes into Protection mode. I’ve never restored a receiver but have plenty of...

    Sony ta-n80 channel blown, cause?

    I made a post a few hours ago about getting the bias correct on my ta-n80 amplifier. I ended up setting the bias after the amp had fully warmed up and everything seemed fine, it kept the bias well and didn't do anything weird. So after this I turn it off, go to test it and get no sound. I tried...

    Kenwood KA-3500 vs. Harman Kardon 330c

    Hello! So this is probably a hard question to answer, and I know there's some subjectivity at play here. But my old Kenwood KA-3500 recently went out of commission (seems to be a blown channel), and it looks like it will be around $150 to repair, with at least month turnaround—which feels like a...

    JVC RX-503BK Blown Channel, But WHY...?

    Hey folks so I have this old JVC stereo receiver that has been sitting around for years because the main fuse kept blowing. So I finally took the time to investigate and surprisingly I found that the output transistors on the left channel were blown. Now I really have no idea what I'm doing and...

    First time poster here.... Looking for any advice on my Sony stereo receiver please!

    Hey guys, I'm not sure if this is the correct place for this post, but I figured this was the forum to join to ask my question. I have had a Sony stereo system with the stereo head and the two tower speakers for about 8 years now (as you can tell I am very un-knowledgeable about audio systems)...
