I recently posted a video describing an adapter you can make, from easy-to-get materials, for using regular D cell batteries in portable tube radio sets that required the obsolete "G" cells (such as the Eveready #964).

URL is http://www.youtube.com/watch?v=VaZCRbY8ihY

I also posted how-to-build instructions to Skydrive at

Thanks for posting this. I saved the PDF instructions in case I ever need to make a G cell. I don't have any radios that need one as yet.

Thanks for the positive feedbacks. I posted to the SkyDrive folder a minor revision to the instructions (some typo corrections that might have been confusing, plus I added a photo of one of my treasures showing installed G-cell adapters).

That's an obsolete battery, but you can string together 8 nine volt Transistor batteries for a plate supply.

If you verify the maximum voltage each tube's plate can handle, most likely you can use ten nine volt batteries, and get better volume. Most battery radio tube plates can handle 90 volts.

"fifties"- Hello, I actually thought about doing that, but feel better hearing it from someone else, too! I haven't heard of anyone else doing that. There will be enough room in the case to fit them all, I will give it a try. Thanks for the advice and I will let you know how it works out!

Here's my RCA 2BX63, which uses the usual battery tube compliment, 1T4 1R5 1T4 1U5 3V4 (although this one uses an extra 1T4 for an RF stage), with 10 nine volt batteries in series;

That looks great. The radio looks like brand new inside and those batteries dont even look out of place. Thanks for posting the picture.

Hello,
Sorry about the broken video link. The white paper link should work OK. I have just restored the video link in my previous post of March 2013. The Zippcast video posting site went off the air for some time. It is back now, so I reloaded the video and edited the link in the previous post. I plan to reload my other battery videos to that site over the next couple of weeks or so.
