Apologies for missing the meeting - calendar /date mix-up !

A quick update on the (original) Hornby sound box :

1. The most impressive part is the steam whistle - really almost life-like - well you know...
2. The most disappointing is the two-tone diesel horn which closely resembles a pregnant duck.
3. Try as I may, I couldn't get any 'chuffing' sound out of it at all. I tried coming off the brushes of a loco and a separate electric motor. I think either the chip has gone down or, faulty component(s) /pcb track.

Might have another go at it when spare time permits.
Cheers,
Dave
