    2226B Balance Knob Issues

    Hey everyone, I've had the pleasure of owning a low-hours 2226B receiver for about a year now, and almost everything about it is perfect aside from the single issue of having an imbalanced balance knob. When centered, the left channel is far more powerful than the right, but if I move the notch...

    Denon PMA-980R channel imbalance.

    Hi. My Denon PMA-980R has an issue with channel imbalance. It's the worst at low volume and gets slightly better when I increase the volume. Someone suggested that it could be a problem with dirty potentiometer. It is a motorized ALPS and I'm not sure whether I can just get a contact cleaner...

    JBL 120Ti driver issue ... Please help

    Hello, I have a pair of JBL120Ti speakers which I enjoy very much. Recently, I realized that the low freq driver in the right channel plays significantly lower in volume that the left channel. I tried to swap the channels on the speaker terminals and this indeed confirmed that the issue is not...

    Yam R-70 ('83) still sounds poor & imbalanced: voltages good after re-cap/reflows

    Service manual .pdf hosted: https://docdro.id/EbfVYvc I've been doing some work (details listed below) on my R-70 and learning quite a bit but it still sounds rather poor as it initially did, also the left channel is weaker. I've tested the device unloaded and all of the PS voltages are in...

    Pioneer SX-780 Channel Imbalance

    Just realized today after fiddling around that my unit's right channel sounds as if the loudness function is permanently on. This was confirmed by the fact that the meters run evenly when loudness is actually on, whereas the right channel is visibly and audibly louder otherwise. I cleaned the...

    The curious case of right channel low end rolloff - Dual 704 w/ Shure V15-III

    So I was busy recording some records when I noticed the waveform in my DAW was noticably bigger in the left channel. It seemed odd, because the stereofield sounded right; vocals/snare seemed centered and overall stereo image didn't seem off. I put an instance of iZotope's Imager on the track to...

    Sansui 800 Channel Imbalance

    Working on a really nice unit right now, Sansui 800, cosmetically very clean, all bulbs light up, everything seems to be great EXCEPT the left channel is very quiet and lacking bass compared to the right. I have THOROUGHLY cleaned all the knobs and switches on the face plate, checked for poor...

    ST70 7199 / 6GH8A amplitude vs frequency

    Ive posted a 1 off video showing my issue of the amplitude change of the 7199 outputs in which the change increases with the frequency. I found something, however even though it corrects the amplitude, the phase does not align, tested with both a 7199 and a 6GH8A Surely this is masking another...
