    I have a pair of Delta 120 power amps, and one of them has recently stopped working. It seems that the speaker isolation relays are not operating (i.e. never closing), resulting in so sound at all from any of the outputs. There is no click when switching on or off.

    The power LED comes on. I've had the top off, and there's no sign of blackened components, nor smell of burning. Everything seems ok. All the internal fuses (I found six) seem ok.

    Anyone got any ideas? I have the tried AC and DC coupled inputs. Source is clean and ok. Amp is not bridged, and set to stereo. (Mono does not work either.)

    Inside the 120.2 (which i owned there are a lot of fuses. Must be a fuse. Just open te top and take a good look and change all the fuses.
