Friends, Thanks to all you helped me identify this beast. It is an NPN Silicon Planar Medium Power Darlington Transistor. Those little puppies are hard to find, but I found them at Digi-Key. Will have them tomorrow. I would send this privately to each who sent help, but most of the messages are on a different computer.
