Today I received the new Soundtraxx Tsunami TSU-1000 #827118 Dual EMD 567 Decoder. I rushed home after work and to my workbench, grabbed my Frisco E8 #2020 Big Red and removed the old TSU-1000 #827101 EMD 567 decoder. I installed the new Dual 567 decoder. WOO HOO! It sounds FANTASTIC! KUDOS to the crew at Soundtraxx! My other E8 will get the same treatment. I can and will use the removed 567 decoder in a GP7 or F unit. Anyone that has been waiting to put sound in their E units now has even more reason to make the move.
