The schematic is available on Nostalgiaair. Go to the home page and click on Rider Vol #1. From there click on Majestic 1-11. This will be a schematic of the Model 90 which will match your radio. Also look on Majestic 1-6. This should be the power supply for your radio.
Look over the tuner is your radio. It has 5 sections and will be made of pot metal. Be sure it can turn without plates rubbing.
