Thanks.. hadn't known of the whining noise problem. Could you tell me again what current is
drawn by the old amplifier. Or to put it in more direct form, if I used an AC adapter type power supply, what
ratings would I need to look for on the product? Of course 120 vac in and then 12vdc out but at what
wattage or amperage would be proper? Do AC adapters also us SMPS in them and do they also cause a
whining noise.... guess I've never noticed any from them.
