Default Stripped Threads in Bakelite

Hi

A quick one out of recent experience with a DAC90A...a definate design shortcoming (daresay in other sets also) is the tapping of threads for bolts directly into the bakelite, instead of moulding in a brass threaded insert. Relies on thick bushes and a fair length of thread to prevent the thread stripping, but...these things happen (one of the speaker mounting points on my set)!

An almost ideal fix is to use a short length of plastic cable tie, trimmed to a suitable size and thickness, inserted into the stripped hole to give the screw something to bite on. Has to be trimmed so as not to unduly stress the mounting bush as the screw's done up, of course, but the squashy plastic/nylon used provides just the right amount of grip.
