Hi Dusty, I've had about 6 fuses blow so far in either of my D200 MK2 monoblocks, it only happens when the power cable is removed or plugged back in. Would you suggest a higher rated fuse than the 3.15A/230V. Thanks.

Note: the amps never fuse when in use, of by the front panel switch. Both amps run off separate mains.

You can use a 4A (fast blow type). The in-rush current can sometimes blow the 3.15A.
