Hi, Hopefully someone can offer advice. Bought lionel SF A&B units 18952 & 18965 on ebay.. Seller claimed “used, but added never run. just tried them and power a-unit works as it should. b-unit electro-couplers work, but nothing I try will get the sound working. I did notice, when I removed shell to install 9V battery, that there is a unoccupied spot on circuit board labeled “Audio Power”. ** Should there be a power module plugged into those pins?** Also, Trainz has a used power board on ebay around $50 total. I am handy, but not a repairman. The trains were a great price and hate to send them back; but afraid of spending the extra money with a possibility the sound still may not work. Advice appreciated.
