Hello,
I have a 75th manufactured in August 2014. Led boards are rev 1.4, and the large ones have a small PCB under the connector plus a wire that was obviously added after the card design. Are these ones safe? Had no problem for 3 1/2 years (game is rarely played) , but a friend with a standard edition and the same cards has leds dying one after the other.... are there also different batches of leds themselves?
