    I hate to ask such a stupid question, but maybe it will help someone else down the road, to have this answered on the forum, because I can’t find it on here or Google:

    What is the physical size of the 3A fuse in the VTA-70?

    These fuses are 1/4 inch wide by 1 1/4 inch long.

    Thanks Bob! So that would be a 6.3x32mm/Large

    I assume a 3.15Amp slo blow fuse would be OK, as it is such a small amount more than 3A.

    Yes ..

    6.3 mm X 32 mm fuse is the same size fuse ..

    A 3.16 amp slo blo fuse will work fine ..
