grundig: 57; UKW-Concert-Boy Dial Glass

Fellow Radiophiles,

I am looking for a scan of the dial glass for the Grundig Concert-Boy 57.

I plan to print the scan on a clear transparency, then place the transparency behind a new piece of clear glass to replace the broken glass. I plan to try using the yellow toner of a color laser printer to imitate the gold paint.

The radio that this glass is for was kindly given to me by RMORG member Ross Hochstrasser.Ross has a very extensive collection of German Radios. It must be one of the largest German radio collections in the USA, if not the largest.

The dial glass can be accessed by removing the chassis. Four nuts hold down the chassis against the  case front, and the speaker wires have to be disconnected. A long nut-driver is needed. Then the knobs are easily removed by loosening their screws. The glass should then be removable for scanning.

This dial has a single layer of paint. The scan should be done with the paint side face down on the glass for sharpest clarity. The scan will show an image in reverse, but this is not a problem.

The scan toning and file formatting is best done as is for a schematic.

Alernately, perhaps someone can sell me a spare glass, or know a service that makes reproductions.

Regards,

-Joe

Dear Joe,

if no other offer has reached you the last days, I may help you with a dial scan from the previous model UKW-Concert-Boy 56. The dial seems to be almost identical with the exception that the lettering "AUS-EIN" behind the volume/ON-OFF knob has swapped the sides. The 56s model says "EIN-AUS".

No idea what has been the reason for altering this... With a picture program, it would be easy to exchange the words to fit originally to the 57s model.

Please compare the dials of both models, I keep this thread for now as a question.

Regards,
Bernhard

Dear Bernhard,

Thank you very much for emailing the scans of for the Concert Boy 56 UKW. I really appreciate the effort you must have taken to remove the glass and scan it.

I have about 90% of the original Concert Boy 57 UKW scale. There is a small section in the center that is broken and is missing.

I will scan what is left of my 57 scale and edit together a full version, by merging with your 56 scan.

I will post the results later,

Best Regards,

-Joe

I managed to merge the end zones of my broken 57 with Bernhard's scan of the 56, and uploaded the result as a schematic.

The scan is at 400dpi in black print. The original is in gold pring. I plan to print my glass in black on a clear transparency, and place a white paper behind the glass in the radio to change the background from black to white for contrast.

I did some experimentation with yellow print on acetate with a laser printer and resulting print is too transparent and non-reflective. My attempts at heat application of gold leaf to the yellow laser acetate printout also failed.

Thank you Bernhard, for making all this possible.
