im looking for a part number off a rci 2990. im looking for the number off the transistor supply voltage regulator. this is the silver things on the back of the radio about the size of a quarter in the heat sinks. if any one can give me the numbers off the back of them i would be much indeed thankful to you. thanks and 73's Doug |

You can use the 2n3771 transistors which is what they use for the rci2995dx. |
