Just bought a KA1102 from an ebayer, NIB. The bfo drifts off and stays off. I retuned the bfo coil but the following week it drifted off again. After the 3rd retune, the screw tower broke while opening the housing. Anyone have the same problem ? Tell you this much, I will NEVER buy a Kaito again. My buddy's Eton blows this 1102 out of the water just by NOT having any problems.
