Complete Tsunami TSU-1000 Digital Sound Decoder

I believe this Decoder is a Tsunami TSU-1000 Digital Sound decoder. I got it a while ago for a BLI (Broadway Limited Imports) Class J steam engine, I had a friend set it up for me so I don't know what the parts are. But I do know that it has a 8 pin decoder hookup and still works. It is stored in an old Athearn box and is very safe actually. It has one loud speaker hooked up to it, and if you are good with your electronics then you can put two in it! I just don't use it anymore. Please ask any questions if needed, I would be happy to answer!
