My Cambridge Audio CXA61 did come with a means lead. If memory serves, the fuse inside the plug is 5A. I lost the former mains lead a couple years ago during a house move. The mains lead I use today, has a 13A fuse inside the plug. Not sure which brand this mains lead is? It's white and 2M long.  Just to be sure. Is this safe, and not causing damage to the amp? Thank you. S. |

A standard IEC C13 lead with a sealed mains plug is all it has, 13A fuse is too big even 5A is large for a 600Watt unit like it is, unless it has a large inrush current on start up which i doubt very much. Divide 240V by the Appliance Wattage which is 600W = 0.4A + 10% = 0.44A.. All you really need is the lowest available fuse which is 3A. But the original 5A will be fine. (Click on the pic)  |

5A seems to be optimum here for most domestic amps except the huge high-current types (such as vintage Krells, you know the types I mean) which can draw 8A on switch-on (and to pass the regs at shows, had to be pre-conditioned before the testers came round to each room to ensure current draw for each exhibitor). I know Naim insisted on 13A or even unfused mains plugs (15A round pin) but they were hobbled designs using oddly doped, sensitive and buzzing mains transformers once made by a now defunct maker in Glasgow (H&F I recall) Sources routinely use 3A nd I even used 2A fuses in some units with thin mains cables (fig 8 types are only 2.5A or so rated). Shane, I'm pretty sure you're way over this thing, but please don't (nor your dad) ever get into foo fuses which don't meet UK specs and which cost a bomb, as it really is snakoil and preying on psychology, illusion and imagination rather than actuality.. RD tried, but didn't get very far I admit.
P.S. My distribution block is fused at 13A I admit but as each unit connected to it has their own fuses, I've kind-of stayed with this.
