'Avo Multiminor' does not have AC current ranges.

I have an Avo Model 8 MkIII that was unresponsive on the 10A AC range, it turned out that the (quite chunky) winding on the outside of the transformer had come adrift at a solder joint. Had it been one of the lower ranges within, it's unlikely that i could have fixed it, but as it was it was just a case of re-wetting and adding more solder.

I can provide photos of the transformer of an early Model 8 if that helps (i have one that is permanently 'open' with all the guts visible)
