Ted S posted:It sounds like this might be an early (<1998) PS1. If you're using a chopped-wave power supply, intermittent or varied chuff rate is a known problem. You would have to use a sine-wave transformer, or put a 150uF NON-POLAR capacitor across the output of your transformer to smooth the waveform.
It is possible to adjust the chuff rate, but as I remember the procedure involves applying power while holding the loco back, etc. That's pretty hard on the motor and tires!!
Ted,
My old K-Line transformer worked for 1 iteration and when I went back and tried again the intermittent chuffing returned. It’s almost as though the engine is adjusting to the transformer for a short while and then reverts back.
What is involved in adding the capacitor to convert the transformer to sine wave?
Also, my ancient 1964 Lionel transformer works great with this engine. Chuffs just fine. Only 1 bell button so I cant work the whistle with it.
Thanks 😊
