DIY on things you don’t know anything about can wear you out in short order. Now I’m a DIY person to an extreme. I built our home including the carpentry, electric, plumbing and most of of the HVAC. I also do all my home maintenance work except I’ve learned the hard way I can’t fix appliances and try to avoid most auto repair.
The thing that wore me out the most though, was trying to keep my beloved old Bang and Olufsen Beogram 4002 linear tracking turntable running. Nobody locally could repair it properly, and I knew nothing about electronics or stereo equipment repair. I even went so far as purchasing a second Beogram 4002 for parts.
As the frequency of needing repairs increased with age, finally the last time it broke down no amount of research and DIY fixing could resuscitate the turntable, I was in despair. Each previous repair had been agonizing mostly due to trying to figure out what needed to be done each time. At last I finally gave up. I threw both the original and parts turntable in the garbage to make sure no one else would ever suffer the same travail trying to keep it running for another forty years. I loved that turntable, and may it RIP.
