I ordered my first K3-100 in 2009 from the factory ( When I decided to buy it, I was eager to have it) :-) Since then, I have assembled kits for another K3-100, two P3's, two KPA500's, a KAT500 and a signal generator boards. All assembled without a hitch. None. Zero. Nada. Sorry about your experience. Mine has been perfection. Jim - W4RKS
