Or ask him to look for the Civil Defense"CONELRAD" Markers at about 640 and 1240 on the AM dial. Looks like a Circle with a triangle inside the area between the circle and triangle filled. If it has them it's a pre '64 model as CONELRAD was shut down in the summer of '63. This usually correlates with the turnover from tubes to Solid State for a lot of manufacturers. Fisher for instance switched over to transistors in the 64 model year on their Lower end models and by the 67 model year had transistioned to Solid State (with the exception of the 400-500C-800C and a few separates. ) Magnavox switched over to Solid State in the '64 model year totally. Some were quick to change, others slower or they just got out of the business. So the Conelrad markers can be used for tube/S.S. identification in about 80% of units.
Just pointing it out. :yes:
