This video shows the troubleshooting and repair (?) of the Leader LG-1311 Function Generator that was shown in a previous video. The previous video showed how the problem with this function generator could have been mistaken for a trigger problem on the scope. The generator had a problem with a low level, high frequency oscillation that was riding on top of the function generator output. The video briefly shows the process I followed to narrow the problem down, identify the offending circuit, and the result of the "repair". I put "repair" in quotation marks because the "fix" involved changing the original design. So, it is still possible that there is another underlying problem that was alleviated by altering the design slightly.
