According to the Bachmann reference: "When used for DC operation, the track voltage at slow speeds is insufficient to power the sound board. For best effeccts in slow speed DC operation , a 9 volt battery backup should be added to the Sierra Sound board as per their instructions." Obviously i know little by asking this question...but here goes: i thought th battery from Sierra was 6 volts. Where do we get the compatable 9 volt battery? i have only installed one Sierra unit and that was a very long time ago. So please, excuse the ignorance.
Thanks for the help.
