Hello, I'm restoring a Beogram TX, and I'm having an issue with the dustcover hinge - it creaks loudly when lifting/lowering it. I've dismantled the hinge several times, tried adding some lubricant between the plastic guide and the plinth, but it doesn't help. I noticed in an article on Beolover's site, that there should be a teflon strip between the plastic guide and the plinth main body, which presumably allows the guide to slide more smoothly; howeer this is absent on my Beogram. Does anyone know the size of the teflon strip and how it is attached to the plinth - presumably some type of glue? The service manual is of no help here Thanks in advance Pete
