Thanks, Albert. Perhaps your clock radio is a good one, but has an original problem, that escaped from the designer. Or even the quality control was no so good as it would be.

It was a very unique trick used by you to fix carbon contact problems, something I have learnt now to emulate as and when found necessary! Many thanks!

If our needs or purpose are fulfilled by repairing it, then why should we throw it away or bury it in the ground? It is better to repair it and use it as long as it is repairable.
