Kenwood Basic M2/M2A Service
I will service your non-working Kenwood Basic M2 or Basic M2A or install modification kits I have available.

Service includes a thourough cleaning of the unit, including the chassis and pc boards. Kenwood utilized a no-clean solder flux during production, which is left on the pc boards. The pc boards are cleaned to remove this solder flux.

A close inspection of pc boards is performed, with a special focus bad solder joints. It is common for solder joints in the Kenwood Basic M2 and M2A to be fractured. This is a common cause of failure, and can also be the cause of popping sounds when the unit is tapped on.
