How to Change the On/Off Switch on a Marantz 2250B Receiver
- 1). Remove the case of the 2250B receiver. Use a Phillips-head screwdriver to remove the screws.
- 2). De-solder the old on/off switch from its solder points. Use a soldering iron to melt the old solder to facilitate removal of the switch.
- 3). Install a new on/off switch for the 2250B receiver. Insert the new switch through the rear of the face panel, and solder the new switch contacts to their connection points using electrical solder.
