Nostalgic KAIEDA MODEL power pack. DC 0-16V (Capacity seems to be around 2.25A, as indicated by 36VA on a similar model.) Operation confirmed with old HO gauge model trains. Can sufficiently handle old Tenshodo locomotives with high starting voltages. This model appears to have been sold by Tenshodo. Please note that I purchased this as a used item, so the usage of the red, gray, and yellow cords and the red and yellow push switches, which appear to be aftermarket additions, is unknown. Original box included. Due to the age of the product, it is sold as-is, and returns are not accepted. #ho gauge #power pack #power supply #model trains #Tenshodo #Katsumi #Endo
