May not have been your radio at all, but instead might have been a "surge protected" multiple AC outlet box. I have a few Tripp-Lite "Isobar" outlet boxes, and if they "catch" a surge, they will make a VERY loud bang! Fooled me for a while until I figured out what was happening. Sounds like some has let off a .22 rifle shot under the operating bench. Dissipating the energy from a big surge take some doing, and the result is often a very loud bang. Might that have been what you heard?
