With the meter set for the 1.5V range, you would read the 0 to 15 on the meter as 0 to 1.5V. So 8 on the meter would mean you are measuring 0.8V. You might have some dirty contacts on the switches or some resistors that have drifted in value.
Having an analog meter is nice when you are aligning a radio. Since you are typically looking for a peak in output during alignment it is easier to distinguish by watching the needle move as opposed to a DVM. DVMs usually are somewhat slow in updating.
I have two VTVMs that I have swapped back and forth on my bench over the years. The Heathkit is a somewhat compact model that is good for general purpose work. I also have a Hewlett Packard 410B that is capable of measuring AC with a flat response up to about 700Mc. That one is a little cumbersome with the way the leads are attached to the meter and the large shielded AC probe.
