Hi All,

I recently purchased a GE Dash 8-40C with DCC/QSI Sound.  I have been unsuccessfully trying to speed match it with a Athearn RTR SD 50 with a TCS T1 decoder.

I have been using Decoder Pro and trying all manner of configurations with both speed tables and changing CV's, clearly I am missing something rather big, I have searched high and low on the internet and have been unable to find the right how to that will allow me to match them.

Resistance is Futile... Ok, If I have a L.E.D that needs 1.5 volts, what resister do I need using 12vdc?

Also I have A 2.4 volt L.E.D I need help with also using 12vdc.

Thanks,

Ernest

Hi, Jack from Star, Idaho.  I ventured out and did some looking at the 70 ton three truck climax that I received as a replacement for the defective shay.  Well I opened up the water tender and found that the PCB had a small motor function decoder with a standard 8 pin plug.  I removed that and removed the PCB to expose the speaker housing.  There I found that a one inch 8 ohm speaker fit perfectly in the factory made area  for the speaker.  No drilling holes or creating an area for the speaker a great improvement.

Hi, Jack from Star, Idaho.  I finally received my three truck 70 ton Spectrum Climax as a replacement for the defective Shay I sent back.  They sent me one that has DCC but no sound.  Where can I find the Tsunami sound chip that is factory installed?  Bachmann shows the speaker but no information on the decoder.  the PC Board shows the motor function decoder but not the sound.  Soundtrax says that the decoder can be added but no information on the part number or decoder number.  Does anyone have any ideas where I can find one of these?  I don'
