Bright orange screen grid
#1

Just noticed a model 70 chassis on ebay, item number 370232120717 (sorry, I don't know how to link. I'm kind of dumb with computers). Any how this guy has this thing running on the bench with no speaker connected! The screen grid of the 47 output is glowing bright orange Icon_rolleyes
