Not seen one of these for ages, the a customer brings in two. I never really got to the bottom of how many variations on the black box amplifier there were. Different controls, different valve line up, EL41s, EL42 etc….. All the usual Hunts capacitors changed and a good clean up. I guess they sound okay, they are what they are!
