1940's Motorola Model 50-X-1


This is 1940's Motorola Model 50-X-1 Standard Broadcast AM radio. This radio is made by Galvin Corporation. The radio was received with no back and I built back with loop antenna similar to the original. The volume control had limited travel (only approximately 90 degrees of travel) and the volume was low. I replaced the volume control and the volume is now acceptable. I had to replace the capacitor on output of 12SQ7 to eliminate squeal when the volume was turned up. The radio works well now.
