Hi
In a box of parts that I will most likely newer use I have some VU meters, old analogue types that used to be very common in audio equipment.
I decided to have a look inside one.
What I expected to find was:
'The original VU meter is a passive electromechanical device, namely a 200 µA DC d'Arsonval movement ammeter fed from a full wave copper-oxide rectifier mounted within the meter case.'
The meter movement was as expected but no sign of any rectifier!
Could anyone explain this?
