[QUOTE="Steerpike, post: 271920, member: 807"] I think you have a wiring fault. The spec sheet says: Current consumption in Test 95 mA in Line Playback 180 mA in Loudspeaker Playback, average level 250 mA in Record 240 mA in Fast Rewind 280 mA Those are all way within the abilities of a 1A power supply. Is the PSU new? It may be faulty. SMPS's have a great sensitivity to their electrolytic caps going dry. Then - unlike linears - they don't become noisy, they just stop oscillating altogether.
