"Tube driven VU level indicator unit", what is that? Why are tubes,
transistors, or any active devices needed in a VU meter unit, the ones I
have are designed to connect directly across a 600 Ohm audio line?
I would like to build a tube driven facsimile of a PPM, using a meter
movement I salvaged from a scrapped transistorized AM modulation
monitor. Any thoughts on a suitable circuit for a project like this?

John Byrns
