What do you sell the battery boxes for? I can do the electrical parts but would like to have a battery that looks original. Thanks for the great video.
Excellent video and thanks for posting. Any idea why the plug/socket is configured reverse of what I would consider "normal", i.e. with the line being female and the load being male?
@@_ferra9288 Yes, the Z-985 battery is used in every model tube Trans-Oceanic radio. The 600 series radios also use an additional battery, a Z-1, for the dial light circuit, and the 8G009 radios also require the Z-1 battery as it has mores tubes than the 500 and 600 radios. The first model, the 7G601 or Bomber model, also requires two D cells in addition to the Z-985 because it too has an extra tube.
Ed: I have one of these radios minus the battery and even has the original tubes. Everything LOOKS BRAND NEW, but the insulation on the wires are crumbling. Any idea of where a schematic can be found, would a slow start up be recommended and are recap & resistor usual for these sets? I don't want to harm this set ****its spent the last 40 years in a closet ****and like i said ***********LOOKS BRAND NEW.
Yes, the radio should be recapped, at a minimum the electrolytic caps replaced. Schematics are available on eBay and can also be downloaded from Nostalgia Air. Go to my website’s resource page and you will find a step by step restoration guide for the Trans-Oceanic radios. The early models used some rubber insulated wires and crumbling ones will have to be replaced.
You could compromise and use 60 AAA cells also. This would be a bit lighter than AA's, not necessarily cheaper though. I wonder about using 75 Nicad or NiMh batteries and then designing an external battery charger.
Not sure what the mAH ratings are on AAA's compared to AA's. The 60 AA's, depending on how often and how loud the radio is played, will usually last in excess of 400 hours. This could be a couple years for many people. By then, some cells may start leaking, so they should be replaced anyway with fresh cells. Even the top brands are subject to leakage.
very gratifying vid! thanks
Thanks!

I don't know the reason. That may have been a Zenith thing as other portable radios I have worked on have the male plug on the radio side.
How do we order one of these from you sir? I am interested in getting one for my H500 I just acquired a couple days ago
You can order online at my website. The URL is on my You Tube channel banner, bottom RH corner.
I’m confessing to being slightly ill informed here. Which one of these boxes do I need from your website to fit my H 500
@@Radionut The Z-985 Late Style is OK for any H500 Trans-Oceanic.
I went with the 10 9v batteries and there usb rechargable same with the D batteries
Great, hope it works well for you.
This pack can be used for all zenith transoceanic ?

I think AAA's are about half the mAH of AA's IIRC, though that depends on the chemistry in question.
