Zenith 5G405

 I don't remember where exactly I got this radio. I do remember someone I didn't know gave it to me at an event, most likely a Studebaker event. At any rate, it sat on my work bench shelf for many years. One day while installing a shop rear water spigot it fell off the shelf and damaged the cabinet when I moved the bench. It's not like this guy was next in line in my "to do" queue but rather something fun to work on. Note that some of these picture are not of the radio I'm restoring but rather from the internet as a reference. I relied on the internet and some folks on the Antique Radio Forum to research some aspects. The battery is an example, I did not have a battery and didn't know what it looked like. Additionally, the radio didn't have the correct connector for the battery. 

Here is a list of items I plan to do to get it looking good and working:

1. Repair broken cabinet

2. Recover cabinet with new cloth 

3. Replace volume knob and repair volume control 

4. Re-plate the hardware (hinges, handle H/W) 

5. Replace all resistors, requires epoxy molding to mimic old package 

6. Re-stuff "waxies" (paper capacitors) 

7. Replace mica capacitors (epoxy molding to mimic old package 

8. Re-can electrolytic cow pasture (large capacitors) 

9. Replace feet 

10. Replace power cord (cloth covered) 

11. Replace chassis wiring (cloth covered) 

12. Repair speaker (patch tears, clean VC, new dust cover) 

13. Replace dial cover plastic 

14. New speaker cloth 

15. Reproduce tube location label 

16. Build/purchase battery solution 

17. Find replacement for the tuning hole brass plug (made) 

18. Repair antenna connector (broken phenolic) 

19. Repair antenna (broken phenolic) 

20. Rewire chassis 

21. Rewire speaker cord 



























































































Someone installed an RCA phone jack and switch to either use the amplifier/speaker or use the radio to drive and external amplifier/speaker, didn't bother to determine which. This will not be reinstalled.


Original decal. Found a new one that looks close to this, instead of "universal" it is "portable"


Speaker is in fairly good shape. Just needs a couple hole patches, clean voice coil interface with pole pieces, and a new dust cover.









Chassis has had a few modifications over the years. A couple of electrolytic cowpastures were added, I assume to compliment the original units installed. Since the original cowpastures will be re-stuffed, the added cowpastures will be removed.



Someone added a tube shield on the 1H5 tube and soldered it to the chassis.
