	i used to have an anytronic amp.. a long time ago. and i think i mentioned it before and Andy Hunt in matrix amps said he'd actually built it? maybe email robin at matrix and see if he can help?

	matrix heritage would make sense, i'm fairly sure these were standard hitachi mosfet units, quite nice amps from memory. likely J50/K135
