mfx High-Efficiency Electronic Circuit with a Sound Effects Generator.

For steam locomotives. This kit is for converting Märklin H0 locomotives with built-in 6090, 60901, 60903, or 60904 high-efficiency propulsion to the new version with a feedback feature and sound effects. The existing high-efficiency motor is retained, the locomotive decoder is replaced, and a speaker is also installed. 12 typical steam locomotive operating sound effects are pre-programmed and can be activated according to the table. Among them are the following special sound effects for specific operating situations:
F8 = simple bell sound.
F9 = sound of bell rung twice.
F10 = sound of bell rung 3 times (provincial railroad).
F14 = steam chest sounds.
F15 = injector sounds.

Also available are the controllable functions for direct control without acceleration/braking delay as well as 3 on-off functions for outputs that can be selected, one of which changes over with the direction of travel (example: headlights / marker lights). Circuit board dimensions: length 35 mm x width 15 mm x height 6 mm / 1-3/8" x 9/16" x 1/4". Speaker diameter 22 mm / 7/8", height 3 mm / 1/8".
