a filtered square wave into a variety of reactive loads.
Has the pre-amp input got at least 10dB of overload headroom above the maximum input signal you are likely to send? Are there any filters at the input of the pre-amp? Do I read >+20dB of gain correctly? There are hints of Walt Jung in the schematics, but whoever designed it, ignored much of Walt's advice.
