A NON USUAL amplifier PLEASE HELP

Hmmmm...

His words were the input is "1mVpp - 10Vpp, adjustable, ALL POSITIVE". I read that as the minimum voltage of the wave always being 0V, with the peak voltage changing, but it could just as easily be +/- X volts around a centre value of 5V, both would give the graph in the example picture. So more information is needed 🙂

By the way, thanks for the DC restorer link, might come in handy one day. It does make the DC offset of the input signal irrelevant but adds distortion (which may or may not matter to the OP)
