Hi All
I have a Bachmann Spectrum Forney 1:20.3 with sound installed.
I would like to connect the sound board to the optical chuff but don't know which pad on the PCB to connect it to.

In other Bachmann locos (K27 and C19) there is a pad on the PCB labelled Chuff.

Any suggestion gratefully accepted.
Many thanks.

I have been working on a new Bachmann 4-6-0 PNP loco #170.
Does anyone know how the chuff mechanism works and if it is adjustable, please?
I am familiar with the chuff mechanism in the Bachmann Anniversary locos.
Is this mechanism the same.

Thank you.
