New K-27 Chuff Board

[StanAmes]

The K-27 was the first Bachmann large scale locomotive with the plug and play socket. The chuff circuit in this locomotive was designed with a chuff that goes positive to indicate a chuff.  While some sound boards work fine with this design, most prefer a chuff circuit that goes to ground to indicate a chuff.  This required the end user to install a transister and often a capasitor in the tender to allow the chuff to work properly.  All Bachmann locomotives with the socket since then have a chuff to ground circuit.

My wife and I have a large outdoor railroad with several Bachmann K-27 and together with some of our operating crew designed a replacement PCB-5 chuff circuit board that incorporates both protection circuits as well as a chuff to ground design.  For a limited time we will be offering these replacement boards for $30 each plus actuall discounted shipping.

   

This circuit board is a direct replacement for the origional PCB-5 circuit board that sits right behind the motor in the K27.

In the above photo, the board on right is the origional Bachmann PCB-5 circuit board.  The board on the left is the newly designed K-27 PCB-5 circuit board.

If you are interested please send me a note.

Highly recommended. my K-27 lost its chuff function last year, and i was offered a trial of this board and it worked as advertised.
