I have an A 30 H2L and I love the ef86 channel. My ef86 tone cut circuit was altered to closer match the old circuit and to give it more brilliance. However I believe on the unaltered circuit you just turn the cut control more to get similar results. Since then I have tried the top boost circuit with bass and treble fully off and get a similar sound which can be made closer by boosting the input or more recently an AC4 Co with the gain increased gives a good close approximation of that sound.
