By the way, it's been great how generous you guys have been with your suggestions, even though I'm probably just as confused as ever. I love all the electronics stuff, I just wish I understood it more, and wasn't so afraid of working on these locomotives. I happen to be a graphic artist by trade, and more mechanical than technical, even though I work on a computer every day.
Well as far as being a regular customer, I was fairly regular for a 5 year period, and spent probably $4000 to $5000 since I've been going there. That's been over 10 to 15 years. Not that I ever kept track, but that sounds like a lot of money to me.
I haven't been there in months, but I did call to inquire. When they see me, they recognize me and Mike the owner knows me by name. Over the phone, I was told, to upgrade my DCS would be free, and to install a new sound file, $10-$15, which sounds reasonable to me.
I checked my 3 TIU's and honestly, it's not clear what the Rev numbers are. One clearly looks like it reads H1, the other I3 (I think) and the 3rd is a puzzle. Rev .1 or Rev .l (I or L???).
Anyway, I hope to pay a visit on Saturday to my LHS and we'll see how it goes. I'm still lost as to what sound file to try on my Y6B. The 5 volt-3 volt, Protosound 2.0, Protosound 3.0 has my head spinning. I've been looking on youtube for videos and just not sure what I should be looking for. It would have been simple if MTH would update the 5v file!
