I'm going to throw something out here: Have you considered Soundtraxx? Their TSU-PNP8 board decoder
https://soundtraxx.com/products/tsunami2-digital-sound-decoders/tsu-pnp8/ can be ordered with a number of different sound profiles installed, they are made here in the USA, they have excellent customer service, they have a YouTube channel, and their sound decoders come with a built in equalizer sound you can tailor the sound profile exactly how you want it. Plus the price is quite reasonable. Before you spring for an ESU decoder, check them out.
I used one for my EMD TR5A project, and it sounds great and performs flawlessly!
It's a chilly, cloudy, windy day today. This kind of weather often makes my right knee act up, so working under the layout on the wiring is not something I want to do today. Maybe tomorrow. I decided instead to start work on a project I've been meaning to get around to for quite some time...
