1  Discussion Boards / Williams by Bachmann / Re: Power Compatibility on: May 17, 2011, 08:58:16 AM

First, thanks for turning me on to a great site -
I installed four diode pairs in my WBB J steamer.  They tamed it a bit but it still runs too fast.  Power is supplied by a 180W Brick ->MTH DCS TIU (which has a starting voltage of around 5V running in conventional).  I'm getting around 50smph at 8V.  I'd like to get that down.  I'm going to try the diode bridges.  It looks like you can get more voltage drop with fewer diode bridges-4 diode pairs reduce voltage by 2.4V and 4 diode bridges reduce voltage by 4.8V.  Do I have that right?  How are they on real estate?  Do they take up a more space than the diode pairs?  (I can always install them in the tender).  How about heat?  THANKS!

Joe, can you explain the Diode Bridges?  I get the diode pairs, but it sounds like the Diode Bridges greatly simplify the process.  I'd like that.  I'm installing in a J class WBB loco (which has barely enough room for the pairs). 


listenin' to the BNSF roll by...

Joe, I tried the diode pairs and I can see that one pair does not really have much effect.  I will need more pairs in series.  If I want to set up four Diode pairs, do I have to do four individual pairs? Or can I just have two sets of four diodes connected together in series and then set up in opposite directions and connected on each end?

Can you tell me where you found the Seuth smoke unit?  I don't really want to order from the UK.  Is there a USA dealer?

Thanks! I found them right away on the Weaver site.  Ordered them tonight - I'm looking forward to receiving them.

I recently bought a set of the ribbed-metal 60' streamlined passenger cars (in my case Burlington).  Does anyone know if there are end-of-car diaphragms available either through WBB or elsewhere?  Thanks!
7  Discussion Boards / Williams by Bachmann / Scale question on: July 22, 2010, 08:11:16 AM
I'm seriously considering buying either the J-Class or the S2 locomotive to pull my classic K-Line Streamliners ("Fleet of Modernism") passenger consist.  The cars are about 14" long each.  I believe these Locomotives are O-Traditional or near-scale.  How can I learn how these units will match up to the consist in scale?
8  Discussion Boards / Williams by Bachmann / Minimum Curve on: May 04, 2010, 10:19:44 AM
I am looking at a set of Williams O 15" 6 wheel silhouette passenger coaches.  They appear to be from either a starter set or a low-end price point set of coaches in Pennsy road name (there are four of them).  Would anyone be able to help me find out what the minimum curve is?
