Hello!
I've got a few questions about remote cut off tubes ( related to varimu compressors).
1. In the definition of the cut-off point two of my sources give very different stories. The first one says:
"in a valve the cut-off point is the minimum negative grid voltage required to stop the current".
While another source says:
" The same increase in negative grid voltage would have driven a conventional tube into cut-off, before the grid even reached - 35 Volts".
But wasn't the cut-off the grid value closest to 0 (least negative) required to stop the current? Because in the second article it sounds as if the cut-off point is the most negative Voltage that a tube can handle ["the same increase in grid voltage would have..."] Could someone please explain this?=)
2. A second little wonder is whether a louder I/p signal results in a more negative or more positive Grid voltage? In relation to my first question, would the cut-off point be the loudest I/p or the quietest I/p a grid can "handle" [required to stop the current]?
Cheers!
