Heljan OO Class 77 Electric Zimo Sound and Stay-Alive
Heljan OO Class 77 Electric with Zimo Sound and Stay-Alive
Kit: MX644D; SuperCap6800; Original Speaker
Very simple install in this finely-detailed model from Heljan. MX644D 21-pin sound decoder plugs straight in. Heljan already
provide a built-in speaker, which is OK, so we just reuse that. It isn't the loudest, and doesn't seal very well against the
chassis, so a little work is required to do that, but otherwise easy.
We also include a SuperCap (via SACC16 kit) for stay-alive - probably a little overkill, as the model picks up quite well, but
this will be running on exhibition layouts, so the more reliable the better!
On track, and sound great with our Class 73 sounds.
