When initially inspected I found several defective electrolytic capacitors, several weak or defective vacuum tubes, one of the dial cords broken, dial window (inside) dirty, telescoping antenna mount defective, analog controls and switches dirty. The 600 series TransOceanic has a slide-rule type dial that's easier to tune and to read than its predecessor.
The front plate also included a momentary-depress dial lamp switch, this was not repaired because it operates on batteries which are no longer made. Also visible on the front piece (at lower left) is the headphone jack.
Looking at the front of the radio, the gold Zenith crest is at the top of the flip-up lid, but underneath it, where the Wavemagnet antenna formerly hung on clips, is a shallow flip-open compartment containing the schematic/service data and the Zenith Dial-O-Map , a compact listing of worldwide broadcast stations and related information. A plastic carrying handle on top of the case. Earlier Wavemagnets were stowed with clips on the back case cover, and it was a bit of a maneuver to get one unclipped, plugged into the back of the radio, and suction-cupped onto a window.
This Wavemagnet is easier to pop loose. You just push a finger up through a hole inside the case top, and when you pull up the Wavemagnet, the cable follows through a second hole in top of the lida simpler solution all around. Another convenience feature is the spring-loaded power cord reel. This is handier than the loose cord of previous models.
The 6 in model 600 TransOceanics indicates six tubes, which are 1U4, 1L6, 1U4, 1U5, 3V4, and 50A1. The 50A1 tube is employed as a "thermal regulator" to protect the other tubes from fluctuations in the supply current. Just as with cars, the model numbers indicate "model years" which may overlap calendar years.
