    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...

    Allison Acoustics drivers

    Hello all I demod a pair of Allison CD-9s today, and was absolutely blown away by them. Unfortunately, I heard a bit of distortion (maybe rub between the voice coil and the Magnet?) in one of the mid drivers (it sounded staticy). Given their odd shape and design, I assumed those things are...

    As per the title I have a beogram 6000 which previously did not have enough power to lower the solenoid. It did try but it would require help from me in order to actually finish going down. I read on a forum that it could have to do with the 1c23 capacitor or the arm circuit transistor. I...
