During an inexplicable urge to do some cleaning up, I found a powersupply for which I have no need. I believe it comes from an Apple (GS II?), and is identified as ASTEC, model AA13591 Input : 230V at 63W, 50/60 Hz. Output : V1 : +5VDC at 4.0Amp; V2 : +12VDC at 2.5Amp; V3 : -5VDC at 0.25Amp; V4 : -12VDC at 0.25Amp. It worked when I dismembered the system it came from. You can have it for P&P ; net weight 1250g Nico
