Hi Bob,
sorry to hear that, but ...... happens. Good luck rebuilding the superstructure. Do you still have the plans? If not, I can make a copy and send them to you.
I did have a little problem with my sound module and the water pump. Everytime I started the pump the sound module came on. Apparently the Graupner pump creates a lot of noise the RAM 82 did not like. I tried different setups for the noise suppresion but no success. Finally, using shielded cable for the module input did the trick. Small problem compare what happened to your Amsterdam.
Best
Wilhelm
