David Bowie sings Rock and Roll Suicide
I was listening to headphones while turning the power on / off. With an MP3 player into AUX1 playing Ziggy Stardust, I heard the music when the power switch was turned off! It took about 20 seconds to discharge the caps. If I cycle power on and off, sometimes the power on results in music! So, when power on gives tunes, the DC offset is: Left = -16 mV and Right = -6 mV. That makes more sense than before. Not knowing the power in wpc, I slowly turned volume up on the Criterion 4Xs and found the sound to be very nice. There's little hum or hiss between songs. The protection module does not have delay - instant on when it works. Running for a while, the big heat sink gets a little warm, not hot. It looks like a rebuild of the Protection Module is in order. Since it just plugs into an edge connector, it should be fairly easy to restore if parts are available. I surmise the power output is in the order of 20 wpc. FM tuning is nice and clean. From what I have read and since no one has offered up any information, this is a pretty rare unit only made for a year or so.
