    Project: Pioneer SX-850

    Another project hits the bench. Pretty busy summer, but somehow was able to secure an unloved SX-850. If you have read any of my threads, you probably know that I am an absolute sucker for the Pioneer SX-xx50 line. Anyone that has worked on this set, knows it is very well built and easy to...

    Help Needed w/ Pioneer SX950

    Hi All, I recently purchased a Pioneer SX950 for a $100. It's in fairly good condition. However, after playing for about an hour, I heard a minor hiss/pop and the sound went out. After some reading through these forums, I was able to narrow down my problem to the speaker protection relay. I...

    Pioneer SX 50 series vs SX 80 series vs SA series

    I realize a similar question was posted a few years ago I just wanted to try and get some refreshed opinions. I recently made the "upgrade" from an SX 780 to an SX 850 and I find myself actually missing the sound of my old 780. Of course I like the apparent build upgrade of the 50 series and...

    Can't figure this one out

    Hello everyone! I have owned a Pioneer SX-850 for well over three years now, and I absolutely love it. It's paired with some refoamed and recapped Large Advents at the moment, which I have had working for probably a year and a half now. I might add, the 850 has been cleaned, and I had to...

    Pioneer sx-850 bias adjust

    I noticed the manual for this model did not show how to adjust the bias. Does anyone know the proper procedure? I assume it is the same as the sa-9500 since both models have a fairly similar output board. Any help would be great.
