Beomaster 6000 (2702) restoration: mounting the FM dial display and fixing a new dial cord

The FM dial display has been restored before (click here). One thing I forgot to mention is the importance to have the dial band under the tiny clips that guide the band in a straight line and avoid it rubbing against the red plexi panel that comes on top. These clips are so tiny that it's easy to not spot them.


On most units that I have restored the dial cord is broken (or about to be). The cords used on a Beomaster 6000 quad are very thin (about 0,4 -0,5 mm diameter)  compared to cords on many other vintage radio's. That's probably why it is extremely difficult to find vintage cord with that size. The best alternative that I have found is fishing line. I know that some hardcore vintage restorers will hate this, but it works, if you select the correct type ! The typical yellow/transparent nylon ones will NOT work. They are to stiff and slippery. I have good experience with high quality DAIWA 8EVO Tournament Braid type of 0,45mm.



There's a drawing in the service manual that describes exactly how to fit the dial cord. Important is the 3 turns on the main pulley, the 2 turns counterclockwise on the shaft coming in from the top and leaving at the bottom.



But before you break your head on this drawing and try to figure out the correct sequence of fitting the cord, watch this excellent videoclip by Beolover that shows you exactly how to do it in this post: click here.

Below is the DAIWA fishing line cord installed on this unit.


The dial cord is attached to the FM dial band with a plastic clip with 3 dents. Best is to remove some tension from the cord before attempting to fix it on the clip. A small dot of glue will help it stay in position once you have the correct setting. Tuning into a known FM frequency and then set the red line to the corresponding numbers on the red plexi display is the way to do it. It often requires a bit of trial & error to get it correct.





The next posts will mainly be on the restoration of the key panel, the red plexi display and the wood plinths. We want this Beomaster 6000 quad to look as good again as it sounds ! And that will require some different skill sets other than electronics.....
