    Check to make sure you put the electrolytic capacitors in the correct polarity. If one was in backwards that might give you the same symptoms. If one is in backwards, it may feel warm when power is applied for a few seconds.

    Did you socket the 14 pin ic's? If so pull them and see if it helps.
    Phil, Still too many interests, too many projects, and not enough time!!!!!!!!
