OK I scoped the saturation voltage of the LM386 and the top transistor is the worst with 1.9v across it when it clips, should this be what I aim for when selecting the top LED/diode series string?
So I just checked on a scope and noticed that the clip LED comes on slightly prematurely, is there any way of fine tuning when it comes on? maybe increasing the value of R4 will reduce the diode current so that it doesn't drop as much forward voltage?
Oh that's handy then, a green LED will drop around 2.1v which is very close to the 2.2v I measured being dropped by the diodes.
Could I replace the x3 diodes with a single LED? As the circuit continuously drains several milliamps but putting a power indicator LED in there would put that current drain to good use especially when powered by a battery.
