I have reciently purchaced a used steam locomotive sound system built by Fyffe electronics. The unit seems to be working properly, but it came to me without the proper speaker decoder circuit. I would appreciate hearing from anyone who might be familiar with this unit. A circuit diagram or schematic would be helpfull, but I will accept anything that I can get. Thanks!
A Fyffe Sound System!!! WOW!!! That’s really an “oldie”!! If you will send me an e-mail at
trainman@operamail.com I will send you a diagram of a filter circuit that will fit in the tender of an HO locomotive and just might work with this system. Take Care and Have Fun…Vic
