Please see pic and thank you for any advice. I will be fitting a dcc 21 pin chip to this 181. Is the chip in the pic a blanking type chip ? Do I just pull it off? Any tips to help me avoid wrecking stuff!!!


Yes the little circuit plate on top is a blank. Carefully remove so you don't bend the pins I used a wooden ice cream stick to gradually prise it upwards one side at a time. Before you remove it, note the orientation and place the 21 pin decoder in the same orientation. Its easy to try and mount it upside down. The pins on the loco board are meant to go through the holes on the underside of decoder circuit board and not directly into the socket (ie the pins end up in the socket but after coming through the decoders pcb holes). One of the holes is a blank to assist orientation.
