Reply to "Lionel 8142-T35 sound board(SOS) repair"

I am still hoping that someone with an electronics background will chime in.
As I have already posted, my 8142-T35 sound board is now working, but at a low volume.
I got out another tender with the same board for comparison, and there is quite a difference in volume.
It turns out that the capacitor that I installed to replace the defective one is too large. The original was 47 Microfarad, 50 volt. The one I installed is a 470 Microfarad, 35 volt. Could this account for the reduced volume?
If so, is a 47 Microfarad, 35 volt capacitor likely to do the job? The voltage is still well over track level voltage. (That is what's available at Radio Shack)
