I recently purchased this radio.  When it arrived I found that the Dial glass was broken -- the radio had been poorly packed.  I found another Concertino 8 and purchased it.  When it arrived, guess what, its Dial glass was broken too.  So now I have two Concertino 8's both with broken Dial glass.  I would be happy if I could make one good radio out of the two.  Please, if anyone should happen to have a scrapped Telefunken Concertion 8 that I could purchase the Dial glass, let me know.  I would be happy to purchase it plus shipping costs.  Thanks

Hello James, I am very sorry to read about your misfortuned case, I have as well purchased a Concertino 8 lately and it's very sad to figure your units with broken dial glass. The Concertinos are terrific radios.

Did you try to fix the glass with cianoacrylate glue while you wait for a replacement glass? If you work with a small amount of glue FROM THE BACK and remove the excess on the front with a blade, most of the times you get fairly good risults. If you then overimpose a new transparent glass, correctly shaped, over the repaired one, in some cases the crack lines may be hidden enough to consider the overall result as acceptable.

Hi Marco,

I appreciate your sympathy.  Unfortunately, both dial glasses were broken in too many pieces to hope to be able to glue the pieces together.  In addition, both dial glasses broke on the same side, so I can't use two to make one (that is use the good right side with a good left side).  I have thought about having a new glass cut, but I don't know how to go about painting the stensil on the glass.

Jim

Hello James. The topic of reproducing glass dials has been already discussed here. The following topic is especially interesting: US fellow Dennis Wesserling shows how to do it with inkjet printers and molding powder, while Mario Coelho and José Duarte Costa go even further with professional-style serigraphy. Results are often "as the original":

You may want to try it on your own or contact those gentlemen and ask if they may do the work for you.

There is even a simpler and faster shortcut: printing the dial with inkjet on a transparent foil, and then put it in a "sandwich" of two glasses. The usual drawback of this method is that white colour is impossible to be printed, but the Concertino's dial has only black and gold if I remember correctly so it doesn't matter. Ther result is obviously not perfect but decent, and it's a speedy way to have your Concertino rehauled rapidly while you work on / wait for something better.

Thanks Marco, I'm going to try the wet decal approach.  I'll have to have glass cut but I know where I can get that done.  Scanning in the original dial will be tricky since it's bigger than A4 paper, but I'll do that in sections anyway, since transfer the wet decals to the glass would be difficult if the decal was that large.  It'll be fun to give it a try.

I have tried to scan what remains of the original dial glass, but since the dial markings are on the back side of the glass and the glass is about 6mm thick, the scans are out of focus.  Any suggestions on how to scan the original and get a sharp focus?

Not really rather than to change scanner type or try with a fine-detail photograph. However, your question risks to go unaddressed here as not many users own a Concertino 8. I then suggest you to open a new, specific topic on this matter and ask other users which scanners have a depth of field not as shallow as yours. Many others probably went through your same problem already and can suggest you a good model.

Hi James:

This is a very old post and I don't even know if you are still watching the forum. I am restoring a concertino eight.  It is missing the grill on one of the side speakers. From your post here, I gather you might have an extra one of these. I am in the United States, so I know shipping will be a little high, but if you get this message and you have one would you please contact me:

mboessen@ktis.net

thanks!

Mike
