Sound Installed Graham Farish N class using a Locoman Sounds Q class file

This model Geaham Farish N class has been fitted with a Locoman Sounds Maunsel Q class file. the decoder is the last stocked of the Doehller & Haas SD05 decoders.
I have used a STACO zimo stay alive circuit with 2 gold cap capacitors and YouChoos sugar curve 7 speaker.
To fit everything in, I cut out the out the coal space and milled out the metal coal representation. this allowed for the gold cap capacitors to be installed.
this model will be used on the Salisbury & South Wilts Railway Society models of Bodmin General, Wadebridge and Padstow as part of their Cornish Lines Project.
