Earlier this morning I had replaced a broken set of convergence rings on one of my K4600s and was trying to fine tune the convergence on it, so you know, my hands are near a powered yoke and anode cap. Well, as I am working on it, this old empty 5 gal tin oil can I have sitting just outside of my sliding glass door made a loud BANG from it heating up in the morning sun whilst I was doing so. My heart nearly stopped and I almost fell off of the stool I was setting on. I actually had to sit down and catch my breath for a minute, I thought it was over for a second there lol. I just finished working on it and thought I'd share so maybe you guys could have a laugh at my expense lol, but it got me wondering if anyone else here had something similar happen to them before?
