A car boot find along with another concert boy that sold. This one is a top end Luxus.

I have one and all I can say is that it rivals any of its competitors from that period, including Hacker, Roberts and Tandberg. A superb sounding radio well worth seeking out. The cabinet can be a bit resonant but you can tame that with judiciously placed sound deadening pads.

Thanks for your comment. Interesting you mention the resonance, we tried using the Luxus as the daily kitchen radio after I became annoyed with the lack of bass from an Roberts R250 that had a speaker upgrade. In the end my wife complained the Luxus buzzed particularly on dialog so it was replaced with a Roberts R900 that’s still being used. To my ears the Luxus has a richer sound but does seem to resonate at times. I tried draft insulation along the inside of the sprung battery connectors as these seemed to vibrate. Also tried PVA along edges of the plastic dial to stop it rattling. Never really solved the problem so would be good to know where you placed the pads.

I used Dynamat Xtreme sound deadening sheet – the stuff used to dampen panel vibration in cars. Basically, I opened up the set and applied it to every square inch of exposed plastic. A finicky job but it made a considerable difference. Still get the occasional buzz but nothing like I used to. Backing off the bass a little helps as well. The Grundigs, as you say, are known for their lush sound. This possibly reflects the fact that the bass frequencies broadcast today are more pronounced than those when the Grundig was designed.
Dynamat Xtreme is quite expensive but a small sheet – sufficient to fit out a couple of sets – is available on Ebay for under a tenner.
By the way, thanks for a very interesting site.

Thanks John, that’s a good idea. I have something similar we used to reduce the drumming on stainless sinks so will give that a try – it was quite heavy material – did the Dynamat Xtreme add much to the Luxus weight I wonder? Yes, the larger Grundig’s volume control circuitry boosts the bass frequencies so with modern boom-boom music stations the bass needs tempering! It’s useful the Luxus has a bass control as well for that.

The Dynamat added a bit of weight. No bad thing. The more inert the cabinet the better. I’ve always felt that this was where the Hackers and the Roberts – with their chunky wood and metal cabinets – had a distinct advantage. Still, the Grundig has its compensations.
