This installation is using the 648 sound decoder, SACC16, Zimo 4 x 220?F capacitors and a Zimo SugarLump speaker fitted to the
current Hornby model. Going with 470uF Tantalums would give even better stay-alive, but anything helps to avoid stuttered
The screw situated under the SACC16 has been replaced with a countersink one and the hole it goes through also countersunk to
to match giving a flat surface to mount the SACC16 or the speaker.
The decoder has been inserted into the recess to the side of the motor. The motor has to be removed in order to insert the
decoder and then the motor put back. The decoder can also be positioned under the SACC16.
Alteratively keep alive capacitors can be strung together and set into the recess on the other side of the motor and remotely
wired to a LifeLink circuit set behind the decoder. This will allow for a longer speaker to be used.
