Kit: MX658N18; LifeLink + 3x 470uF Flat Tantalums
Another wonderful model from Bachmann, the 1P is well designed, with DCC Sound in mind. It comes with firebox glow (2 LEDs) and
a SugarCube style speaker on board already, so if you just want simple, then the MX658N18 sound decoder is a piece of cake to
3 screws and the body pops off, take out the Next18 blanking plate and put the MX658 in, and you're done!
Just being nosey, we have a peek at the speaker box, which is securely screwed on underneath. This also reveals a line of
solder pads, which Bachmann have very thoughtfully provided for us to add stay-alive and even extra lighting if we wanted it.
We'll just go with a small stay-alive.
Just because we are super nosey, we disassemble the whole loco to see what other space there is, which reveals a little room in
the bunker - could be used for more stay-alive potentially. We don't bother with this installation, but it is just interesting
to poke around!
Instead, we add the required wires for stay-alive (+VE and GROUND) to the provided pads on the model's PCB.
The stay-alive kit is connected... 3x Flat 470uF Tantalums and the LifeLink PCB, then this is connected to the blue and grey
wires that we added previously.
Wrap the stay-alive in Kapton tape and place losely above the decoder. The fit is quite comfortable in the curve of the
boiler, and this improves running enough to make it worthwhile.
The model reassembled and working very nicely.
