Hello All

Wondering if there may be another out there with a Coradio? This is a coin op radio from the 1940’s that was used in hotel rooms. Am only of course.

I just acquired one in what I would consider really good shape. Completely works. Just needed a wipe down.

Wondering if there is any info out there such as schematic etc. I went on antique radio.com and found a scheme that seems close but it uses a different tube complement.

Hoping there are others out there with this piece of Americana from post war times when this country had its foot to the metal!
Thank you

George

I am of no help, but do you have a picture? That is super neat!

#3 1 year ago

I remember those! Sometimes the room also had a vibrating bed you payed for! Better times!!

#4 1 year ago

I have two of those. What do you need?

Hello

And thank you. Mine looks just like yours. Was hoping to be able to at least get a new tube complement that goes by the rear of the chassis. Mine is getting unintelligible. Also any documentation that may exist. Neat little radio. Love this coin op stuff!

I also remember the vibrating bed devices as well. Guess I’m showing my advanced age!

Thank you All!!

I have no documentation. I bought the AA5 handbook. That and others were no help in repairing both my units. I bought a parts chassis from the guy I got these from and swapped in the whole unit. Usually, a re-capping will bring these back to life.

#7 1 year ago

Ok. Is your tube listing inside the back of the unit readable? If so could you take a picture?

#8 1 year ago

Original chassis. No labels.

Donor chassis. No labels

Ok. Thank you kindly for looking. Right at the back of the chassis by the retaining screw affixed to the cabinet was a small tag with the tube complement on it. I’ll take a couple pics.

Lucky you. That thing looks like it has already been re-capped. That label does look familiar now. Mine was in about the same condition. I looked back in the garage and could not find it in my hoard of stuff. For the age of this radio, that label looks to be in "good" condition. I would not change out that yellowed one with a crisp new white one.

Both of my radios have "12" series tubes in them. I believe one of them is an actual chassis for a Coradio.

I will follow your advice!! Thank you kindly!

Hello

Did see that but the tube complement is different than mine
Thank you. Have requested to be a member of their site. Ty

You have a working item that has re-capped. I see markings on your tubes that show they have been recently replaced. Your radio will give you years of enjoyment as-is. What are you trying to accomplish?

#18 1 year ago

The AA5 was mass produced and readily available. The Coradio went with six tubes and these were not as common. I did not find the information that I was looking for at that time. Unless you got crazy with contact cleaner or got mica migration, a re-cap is all that is needed for maintenance. Yours has been recently serviced and will last a very long time.

#19 1 year ago

Would you mind sharing how you removed the chassis from the enclosure? I have removed the two front knobs and the screw in the center back of the plywood base. Doesn’t seem to want to move??

#20 1 year ago

Remove the bolt or bolts from the plywood base and it should slide out with the plywood. This is a dangerous radio and needs to be electrically isolated from all metal parts.

#21 1 year ago

Thank you. Must be doing something wrong. Ty

#22 1 year ago

Figured it out. The two small rubber feet in the front unscrew and allow the front of the chassis to become loose from the cabinet.

Was able to document the tubes that are in place and affix a new power cord that won’t cause a fire!

It has been recapped!

#23 1 year ago

When putting it back in, make sure that the knobs are not touching any of the chassis. Do not turn it on unless the knobs are on.

#24 1 year ago

Thank you. I did insure isolation. I guess this kind of design would not fly today. Hell everybody be sueing everyone

#25 1 year ago

Looked up AA5. Stands for All American 5. This refers to 5 tube radios made in the period of 1940’s approx. the Coradio is slightly different in that it uses six tubes. Just thought I would put this out there for others that may not have been familiar like me.

#26 1 year ago

One should know or learn about the AA5 when working on vintage radios.

#27 1 year ago

Fortunately I did not have to work on this radio. Save for discovering what tubes are actually in the unit(which is different than what the tube complement says) and replacing the power cord, that’s about all I wanted/needed to do. I understand and appreciate the need for the chassis to be isolated from the body of the cabinet.

I’ll take some time and read about the AA5 radios. I am new to this so time will be needed to learn a bit about the type of radio. Thank you for your help!

My hobby is quite broad. I run all over coin-op, pinball, video games and EM machines. There is no way that I can be an expert at all of it. I focus on the project at the time and move on to the next. My help is based on what I did at that time and what I can remember from it.
