6L6 grid resistor values

[Tdale]

On the hybrid-a schematics is shows 3,3K or 5,1K on the input grid, and 1K on the screen grid.

I used 470 ohm on the screens, and 3,3K on the input.. What do you guys use?

No problem with the 470 on the screens and 3.3K on the control grids, as long as you stick w/ 6L6's - EL34's although require 1K/5W on the screens and (at least) 5.1K on the control grids.

I'm usually using 10K's on the control grids, the increase still isn't inaudible, but with 10K's I feel more on the safe side against possible RF oscillation in the power stage.
