Manual repair of just about everything was worthwhile to do back then. Partly it was because labor was cheap and physical stuff was expensive (which has inverted) and partly because the overall <pick the appliance> was well built enough otherwise where one could expect to get years more service out of it post-repair. This approach doesn't payoff nearly as well when everything in the device is engineered to be within an inch of it's life once the warranty period ends. (if you're lucky)
