There is 3.3V Regulator(U5). The parts name is LM1117MPX-3.3 It is SOT-223 package. Thanks

Thanks peter. I could read that one. The one I need the info on is right before the 3.3 it is the orange one right next to the power and before the 3.3

You can use general tantalum-capacitor at C19. It is 10uF/16V and B-case(3.5mm x 2.8mm). Thanks.

Would it be feasible to use a resin dipped tantalum capacitor or best to get the same thing as the board has already? I guess I’m asking if there is a major difference. Thanks. Youve been a marvelous help

Thanks Peter. You wrre a great help in tracking down that capacitor. Went to radio shack and found a standard tantalum cap with pos and neg leads and soldered on board. Back up and running. 10uf16v of course. Thank you.
