Default Re: AVO VCM163 - Some faults I have had

And here is a corrected schematic of the VCM163, the corrections are:

* Connections for C2, C3 & C4 corrected, previously on wrong transformer tags
* Wires added for S3E connections to S3D for Ia positions 3, 10, 30 & 100 mA
* Meter M1 & M2 correct resistance values

* Meter M1 contains compensation resistors and one NTC to adjust for temperature drift, otherwise the meter movement is identical to M2 with a coil resistance of 1500 Ohm +/-1%
