Sony STR 6800 SD

[Blue Shadow]

Just fyi. This thread is over 5 yr's old. You might want to PM him to see if he still has the parts unit though and good luck.
I love my 6800, Nice unit.

By quoting the post, there will be an alert on bigears page that can link him here. He should see it.

uneven channels



Mine has a weaker (maybe 15%) right channel. I need to set the balance between 1 o'clock and 2 o'clock to get a centered stage.

I have cleaned all pots/switches except the volume - wasn't able to get any deOxIT inside the black cover around the volume control. I checked DC offset: 19mV for the left channel, 32mV for the right channel.

Based on the above info, could a dirty volume control be the culprit or is it more likely to be something else?

Thanks in advance
Ben

I understand this thread is from a year ago, but I was wondering what the resolution to this issue was? I picked up a near mint STR 5800 at an estate sale for $25 that I have mildly cleaned the controls and have been using it now for a couple of months. I have noticed the same issue with my 5800, low right channel volume that requires offsetting the balance. I have been researching cleaning protection relays and came across your post. I will be taking mine out of service to change a bulb and perform a more thorough cleaning. I found DC offset to be ~19mv and 23mv well within the "acceptable" range.

The receiver sounds great, even with diminished right channel volume and I absolutly love it. I have replaced the fake wood sides with solid walnut and want to get the electronics as good as I can. Thanks in advance for any help.

I love the walnut panels you put on! I need a set for mine....... The one feature I love is the "Acoustic Compensation" switch and I love the position of the volume and tuner knobs.

Thanks BodyBlue, they are fairly simple to make, the original is a setup guide for tablesaw, router table and drill press. The only slight tricky part is folding the front edge to wrap the grain around and hide the end grain. I considered making more to market them but not sure if there is enough of a market.

I love my 5800, I have a FM Stereo lamp to replace but I am really interested in sorting out the channel difference. It is not horrible to deal with I just want this receiver pristine. Any help in this area would be appreiated. I may start a new thread as this is for a 6800 and I am not trying to hijack.
