In early October 2021 I arranged for a very reputable train repair business, who is one of our Forum sponsors, to fix a LionChief+ locomotive in which the smoke feature was not working. It otherwise worked fine.
Th e smoke feature of this engine is still not repaired because the repair business tells me it needs a new circuit board and they have been unable to get that board.
Have such circuit boards been very difficult for train repair businesses to get since October 2021?
