seems there was also a voltage problem -100 was down to -13, something shorted, 50 ohms to ground, was not there before.
did not take long to find, something on the audio amp sub chassis, unplugged it, and -100 came right back up, and 1st amp came to life.
just have to find what failed on the amp later.
the sound heard is as always is the fans of my servers.
