I sold a Croft Micro to far away, double boxed it, the buyer didn't want insurance. It arrived faulty. No blame on me from the buyer, but the involved carriers didn't care. They offered to refund the postage.
I am grad you ask, Bish, you beat me to it. My power amp has 22K input impedance and input sensitivity of 1.5 V which I can also change through the feedback resistor. So will it work?
