A VTVM or FET voltmeter is highly desirable for alignment.You adjust a trimmer or inductance to get a peak response. This is easier with a VTVM or FET meter because the meter response is quickly observed after an adjustment and you observe when the needle reverses indicating the peak has been passed.With a DMM there is a longer settling time after adjustment and you have to remember the last reading to detect passing the peak rather than watching direction change of the needle. I have no experience with an analog DVM.
