FOR DAN PIERCE - I recall that you converted a customer's LGB 20215 to a Zimo sound decoder last year. I'm using a Massoth LS sound decoder to replace the factory electronics. I note on the existing circuit board a small additional circuit board that powers the locomotive's front lighted Christmas tree. What does that circuit board do for the lighted tree: I measured the input to that board at 6.3 volts and output to the tree at 17 volts? Should I reuse that circuit board on the output of the Massoth decoder's terminal to the tree?
