Obtained this ST700 Sound Trak by Tri-Tec of Chicago years ago, but missing the manual and power supply. It appears that this product and firm predated the internet, as little info seems to be floating around.
I believe it was marketed largely to G scale modelers, and it had the capability of sending the sounds over the rails to a receiver in a locomotive or train car.
Might anyone have one of these? If so, I’d love to know the specs on the “wall wart” power supply — I found a photo of one online but can’t quite make out the info. (I think it’s 20 volts but can’t tell if it’s AC or DC).
Also, while I have my hand out, a scan of the manual would be great. (I have the first page from my internet search.)
Thanks!
