GamuT Di 150 Dual Mono Amplifier

This lit up all the input selection on the front display and nothing else, the -15 V regulator was overheating. The front panel has the remote sensor, volume motor drive and input selection controls, something was shorting out. I removed the long ribbon cable to the panel and manually selected an input relay by wiring links in the plug, worked fine - contacted GamuT to see if spares are available no response as yet...

Gamut (Denmark) got back to me with some info; a schematic and component ID. I repaired the amp, the 5v regulator was faulty, the fzt transistor and 317 regulator (all smd components) were replaced at the same time as they had suffered from heat overload.
