Example 1 - Heljan OO Class 35 Hymek with Zimo sound

Kit: MX645R; YouChoos IceCube28X18X07-2W speaker

Really simple installation in the Heljan 35... MX645R just plugs straight in, and the 7mm dual IceCube goes on top without any modifications, and sounds fabulous too!

Hydraulic heaven as our Hymek emerges from the tunnel!

Example 2 - same, but a little stay-alive added too

Basically the same approach, but we've included 4x 470uF Tall/Narrow Tantalums capacitors in parallel, which then connect directly to the MX645's 'other' blue and grey wires. It isn't much stay-alive for this heavy/hungry model, but everything helps.
