Large / K-27 Chuff transistor circuit
January 16, 2008, 07:46:40 PM
 ;D I thought I would update the forums on this chuff transistor circuit. I was informed of this transistor circuit last weekend at the Del Mar Train Show. Stan Ames sent me the transistor ID and information on how to install it.
The circuit is now up and running in my K-27. It is powered by an AirWire controller fed from two lithium-ion batteries, wired parallel, located in a trail behind battery car. The sound card is a Pheonix P5. Both came from Jonathan at Electric Model Works.
The chuff circuit is performing perfectly. I am getting the exact sounds from the sound card that I programmed it to emit. It is using the chuff circuit as it's que. Now this K-27 looks and sounds just like the real Mc Coy.
I do not know,as yet, how to post either pictures or attachments to these forums, but if anyone would like to know any information on this circuit, how it installs or how it works, just send me an e-mail and I will be happy to help. I will be gone till next week on a clampper outing but will be returning in time to watch the Chargers and New England play, yipe!
As stated above this circuit came from Stan Ames. If this did not work the magnets on the axle were plan "B".

That's it, everybody out there take care,
Large / Transistor for K-27 Chuff Circuit

Can anyone out there tell me what transistor number is to use in the chuff circuit on the Bachmann K-27's? I have a diagram of the circuit that I picked up at the Del Mar Train Show today here in San Diego but I forgot to get the transistor number so I can run over to radio shack to pick one up.

Are the Bachmann folks having problems with their web site? Quite a few times now many of us have not been able to reach the site. Just wondering if you folks are experiencing some puter problems.
