Hi Spider,
Does your V-7 work ok?? The test leads on measuring DC will be the ones marked com which is - and the one marked DC (with the function switch on DC+). You may want to go thru the manual and make sure that the calibration it good and all of the functions are working. I'm always suspect about ebay purchases not that there all bad but most of the time the seller has no clue as to what their selling or the condition.

Just serviced a V-6 about a month ago for the same reason, needed it to measure AVC voltages on my old HRO. As for the avc line you can find it at the junction of #41 and 42. Would use the 15V dc scale. Select DC- on your meter connect the common to the chassis and use the probe connected to the resistors.
