Default Re: AVO Multimeter survey

Mike, from the top the bobbins should be 50k,50k,60k,30k,8kohm. The 2kohm bobbin serving the 5v range is slightly inboard- so geographically speaking they are 'one out of step' if you see what i mean. Sometimes there is a slab winding obscuring the lower bobbins, which i think is a compensatory shunt to improve the accuracy of the 5vAC range.
