With your commentary Veteran, the best learning points come in your discussion of what you are doing with tearing honesty and immense quantum of experience and wisdom that pours out. It is a video I will use to go through a few times while I try and repair some old speakers I have (old, meaning Vintage, from the 2nd WW). It is the small things that put the big task together. I am not old, but a younger senior and I know what limitations come by. Given a couple of passionate learners under you, they would make great experts and professionally really good and well informed. Good Luck sir.

Nice video and a great job.
