i have a system that consists of a 12 volt 18 amp hour battery, a planet audio BB1200.4 class D 4 channel amp, a JBL GT5-15 sub in free air, and a battery tender charger. at first, i was using proel flash 8p mini PA speakers as mains, but tonight, i hooked up a brand new pair of JBL Northridge...
I collect old vhs, and recently got some cool gimmick ones that light up when you press a button. However, they are almost 30 years old and no longer work.
Taking a look at the pcb both were heavily corroded. I scraped off as much green corrosion as I could and replaced batteries but no luck...
