Corresponded with Midge in 2009 about a MTH smoke unit to installed in a reg regular loco to run off track voltage between 12-16 volts her response below . Bought it back then hooked up some leads and tested fine just not installed in any engine as of yet.
Just checked that part number on MTH site AA-0000011 and it now cost 65.00 instead of the 50.00 paid back then 10 years ago and S&H probably is more as well.
Dear Martin:Thank you for the email below.That voltage, 12-16VAC is fine. The AA-0000011 smoke unit is fan driven and will operate properly at the voltage listed. I The part number is AA-0000011. The cost for this smoke unit is $50.00 each Shipping & handling is $6.75 . Hope the above information is helpful.If we can be of any further assistance, please let us know.Have a nice day!MidgeParts DepartmentAt 04:58 PM 10/12/2009
