Working on a Baracora I found no 5VDC on the Sound Board Test point. I noted that the 7805 was hot. I removed the 7805 and measured 1.4 ohms between +5VDC and Ground indicating a short somewhere on the board.
Almost all electrolytic caps have been replaced with orientation triple checked. I Checked all of the little glass caps with a magnifying glass and none looked burned or different from one another.
What are the possible shorted devices that would be high on the list to lift their 5V supply line?
