How about the best of both worlds?
It really is Electronic but it drives an Analogue Meter. The LCD changes to match the Range selected.
Quite amusing really
Seriously, this topic is circled on most Fora at some time or other. It tends to generate more Heat than Light.
I use both - my AVOs for old Sets where it was what was used for the Service Manual and modern ones for modern Equipment.
I've even got a splendid Bench DVM with fearsome accuracy if I really want to measure something.
I've long been of the view that the fundamental question is 'Do you know what you're trying to measure?' and 'What variation is acceptable?'. To put that into a simple context most old Radios, and a lot of Test Gear for that matter, were built with 20% Resistors. With luck there'll be two or three Mains Taps so you'll get withing a few Percent. The Valves will age but still give acceptable Service. So, if the Manual says the Anode Voltage should be say 220v what will you accept? with which Meter? before you start changing things.
