What does it mean when the ioc lights stay on.

The on off switch doesn't work on my other d150.

I want these fixed cause I love them, their so clean sounding.

Although we no longer service the D150 amplifier we still can perform most service on the D150A and D150AseriesII.

Most of the parts are still avialable from or parts department and if needed the service manual is available from our web site at:

IOC is the input output comparitor and indicates if there is greater than 0.05% difference in output from the input other than amplitude. If IOC is continually lit you could be many things. I would first check the output devices and the ouput drivers.
