Zenith Trans-Oceanic
Model 8G005YT
1946-1949
At right and below, is a Zenith Trans-Oceanic 8G005YT in poor condition that I just acquired for restoration. The 8G005 uses eight tubes; all loctals, except for the rectifier, which is a 117Z6 glass tube octal. The audio output uses two 1LB4 tubes in a push/pull circuit, providing excellent sound. Because of the extra tube lineup, a 1.5v Z-1 type battery has to be connected in series with the Z-985 AB battery when the radio is operated on battery power. The extra 1.5v is added to the filament circuit (A+). The 8G005 series radios were the first post-WWII Trans-Oceanics, and are considered the most electronically complicated of the Trans-Oceanics.
Cosmetically, the radio cabinet is in very poor condition, and I've purchased new Tolex Black Stag vinyl to recover it. I will also need to make a new dial cover as the original is yellowed and has shrunk and warped somewhat near the top as can be seen in the photograph to the right. The brass dial bezel has some pitting, also near the top, and will need to be refinished as well. The radio is complete, including the original knobs and all three antennas, along with the suction cups, connecting cable for the two Wave Magnet antennas, and the retaining clips. The whip antenna is intact, not bent, and extends and collapses smoothly.
Electronically, I don't know the condition of the radio. I haven't yet removed the chassis. I did pull and check all the tubes, and found one bad tube. I won't test the radio until I've recapped it and checked all the resistors. The wiring to the battery connector and the power cord is in bad condition, so I may find some deteriorated wiring under the chassis as well. The dial cord is broken and will have to be restrung. As the bottom picture shows, I have already removed the back for easier access to the chassis.
Personally, I think the 8G005 series and the similar G500 are the best looking of the Trans-Oceanics.
I will post updated pictures as this project moves along.
