I am trying to find a replacement speaker for my SD90 mac.It is a 50mm 16ohm 5 watt.I have tried to order it through the MTH website which said it was in stock but apparently the order never went through.I left emails with the parts dept. and finally talked to a clerk who took the order and said they would send it out.It has been over three weeks since that conversation.Does anyone know another source for this speaker?.I also ordered parts from the Lionel website and they shipped it out the next day.
