Re: Mullard 3-3 voltages query
You didn’t forget to fit the 10MΩ grid-leak resistor on the EF86, did you? I’ve done that myself with this amplifier - easy to miss because in many/most input circuits you might be expecting the grid to get a DC path to ground through the volume control. But in this circuit the v.c. is AC-coupled to the grid, so the valve really needs that 10MΩ to ground.
