Hornby OO A3 Flying Scotsman (8pin tender version) with Zimo sound

Kit: MS450R; dual SugarStrand25X20X09 speaker

Fairly simple fit to the 8pin tender version of Hornby's A3 in OO. We have to cut away some of the plastic slope under the coal load, but this is hidden and easy to do. This frees space up for a very decent dual SugarStrand speaker.

The MS450R just plugs in, and speaker is mounted on some BlackTack at the front of the tender below the opened-out coal chute. The sample 1000uF capacitor (for a little stay-alive), is wrapped in Kapton and fixed down in the well of the metal weight.
