Diesel Dayz Posted February 13, 2017 Share Posted February 13, 2017 Hi Guys. I'm trying to do a bit of a swap. I've took the sound decoder and speaker out of a Bachmann 37 (32-775) to put into a different Bachmann 37 (32-783). The problem is the circuit boards are different. On the original the speaker wires are soldered direct to the circuit board. On the loco sound chip is now fitted to I have got 2 orange wires from the speaker and nowhere to put them. Any ideas? Thanks in advance. Link to post Share on other sites More sharing options...

Thanks in advance. 32-775 (37 038 with buffer cowls) originally had an 8 pin circuit board, whereas 32-783 (37 049) has a 21 pin version ? Is the decoder your using an 8pin or 21 pin ?
