Reply to "RS2 sound failure in Lionel Hudson "Yellow Belly" 6-18043"

Not likely the LCRU. The Commodore tender and the Yellow belly tenders are not wired the same. The Commodore tender has a four prong plug and the C&O has six. While both tenders have the same plugs for the circuit board, they connect to different pins in the tether. I highly suspect the power and ground pins. The guys at Lionel service should be able to supply you with a modified wiring diagram with the correct pin-outs from the six prong plug to the 4 prong plugs. Once you get that figured out, you might be able to use your original PIC and ROM chips for the original soundset.
