Up for sale is a Trix UP Big Boy (2005 Version) ESU LokSound sound decoder. Item is listed as “used” but is in excellent condition. This decoder came out of a Trix Union Pacific 4-8-8-4 Big Boy (2005 production run) that has since had an aftermarket sound decoder installed. The only reason why it was removed was because my preferred decoder brand was installed in the locomotive, the ESU sound decoder functions very well and has no issues. It has been reset to factory default settings with an address of 03 before being removed from the locomotive.

PLEASE NOTE: This decoder is an early ESU LokSound decoder that requires a 100Ω speaker (not included).

Item will be shipped via USPS Ground Advantage. Item is sold as-is and returns are not accepted. Please examine the posted photos carefully, what you see in the photos is what you get. I will combine shipping for multiple items purchased.
