Hey, Thanks guys for the replies. Fortunately, the seller agreed to let me return the loco for a complete refund. As a Power Transistor Reliability Engineer for many years, I have run across situations where an intermetallic compound can be formed by separation of the alloyed materials. In general, this condition is brought on by the application of temperature significantly higher than room. I hope this is just an isolated instance and ahs been brought under control by the factory making the units. Thanks again and best regards,
