I'm thrilled with my return to clarinet playing and making great progress, but I'm unsure of DIY repair and maintenance value. I tend to value independence and willing to learn, but I rather devote my time to the musical performance skills. I am to decide whether to invest in tools, supplies, learn from U-tube videos and probably buy a cheap sacrificial instrument or simply take my needs to a local professional. Presently, my clarinet is in fine condition, but I need a tendon joint cork replaced at the bell; a small cork cushion pad on my register key and a single pad adjusted that is not closing tight on one side. What are the experience thoughts from this community? I have a 1975 LeBlanc Noblet in very good condition and very suitable for my present level of skill. Is there some intrinsic value in caring for all yourself? Should I expect quality local repair to be common and easily found in most major cities (I'm a frequent transient on the US east coast)? What's your advice?
