    Strange Kenwood KR-7400 Connection Issue

    Hey all, I have a Kenwood KR-7400 that has incredibly weak audio in the left channel in all modes except for aux. I have deoxed and flushed every switch and pot in the unit multiple times, hit the quad separate switch on the back of the unit as well. What's odd to me is that both...

    Denon PMA-850 Troubleshoot

    I've got a Denon PMA-850 with a weak right channel (also sometimes distorted, but mostly just weak). Balance pot resistance wasn't reading evenly between L/R channels so I replaced that with a new Alps pot thinking it would fix it but it didn't (VR4 in attached pic). Issue is not in the power...

    AKAI X-150D w/Super Weak Right Channel

    Hello! While I know it has little value I'm still trying to resurrect this 150D, but I've run into a hitch - during playback the right channel is quite week while the left is strong and clear. Again, there is signal on the right side but it's mainly hiss and a low level of the music from the...

    Hi! I'm new to tube amps so asking for help to determine what is wrong with my Scott 222. I observed that the LEFT channel has a lower volume than the right channel. I did some rough testing with a phone app and the left channel seems to be about 4-5 decibels lower than the right channel. So...

    Sansui 7070 Weak Left Channel & the Dolby NR Button

    My Sansui 7070 has been with me over 4 years ago, but was neglected for the past two years. Recently I took it out and play it again, found that the left channel is rather weak and scratchy. Random fiddling led me to discover that if I press the "Dolby NR / 4 Channel Adapter" button (which will...

    Hey everyone, I have a Kenwood KR-4070 that I've used for about two years now with no problems but recently I noticed that the right channel is very quiet, but only while running through either the Aux or Tape inputs. The Phono input works flawlessly and has great sound through both L/R...

    Receiver has dead channel

    Hi all. Hope I can get some help here again... I retired recently and took up electronics (specifically vintage audio). I'm not a tech, and have minimal knowledge, but decent skills, and a love for vintage audio. So, I got hold of an old Allied model 355 receiver (I guess it's made by Pioneer)...

    Yamaha CR-800 weak right channel

    My 800 sounds weak from the right speaker. I've swapped the speakers, and ruled that out. The volume is about half of the left side. Sometimes it comes up higher if I flip the High-Low Filter switch a few times. I'm wondering if there are some things I can look at before I give in and go see the...

    Harman Kardon 330b - Left channel is there but much weaker than right

    OK. I'm working on a nice HK 330b. The left channel is very weak. The only way I can get the channels to "balance" is to turn the right channel down about 85% with the balance knob. The sound is not distorted, just very, very weak. That's not good. Here's what I've done so far: cleaned all...
