DCC decoder

I have an older DH121 Digitrax decoder that the headlight circuit no longer works.  Is it possible it has a bad diode that can be replaced?

Anyone remember the Mod to slow down Booster 5 was Recomendations for new DCC boosters.

All; it turns out I had another booster 5 still in the box I had bought, so I guess I'll try and mod the booster 5's to slow them down, I know if you change R5 to 19.6K  it slows the trip time to 130ms, is this slow enough or is there a different mod I need to try and find somewhere?? I'm going run the EasyDCC setup until it gives me problems and then switch, I can't justify changing at the moment. Thanks for any answers you can give.. I tried wading through the EasyDCC forum, but it seems like anyone who knew anything about it has moved on.

Wiring a helix...

OK I have my plan for my staging and then some... Now for some questions regarding the helix.

1) I have taken your advice and split the lower staging from a "80ft run" to about 40ft by 40ft.

2) At the end of one run there is a helix. it is 2 levels (33inch rad.)

3) It goes up to my yard on the second level.

How do we deal with this. Before I started reading up on this stuff I thougt that I was OK, now I realize there are some parameters that I need to consider.

O Scale DCC/sound question

I have an older Atlas SW-9 in mint condition.  It has a single can motor and runs like a watch, less than 1 smph both directions, competely silent.  What could be the problem?????  High stall AMPS over 2.5.  It would definitely smoke a Tsunami.  Josh at Tony's Trains says the QSI Revolution U can handle it..............I'm not so sure about that.

Anyway, I'm curious what others are doing to add sound to these big fukllk size O scale locomotives???

Thanks,

Peter

An N scale AC-12 in a far flatland: Italy

As this place seems "immune" from the Intermountain's AC plague (Ho model seems to suffer of never end discussions and some N scale too), well, mine run nice from the beginning!

Program Track - Dumb Question

Working on my on an area of my layout that is in a hidden area with the workshop. In addition to the other "regular track" in the shop area, I wanted to add a spur for a programming track. My initial design calls for use of a turnout from the main to the P. track. For a number of reasons this connection (turnout) would be cumbersome and I am realy not happy with what I have come up with so far. Then it occured to me that I really don't need to connect the two. I mean, all of the track is hidden anyway.

Decoder install: Athearn RTR SD45 & SD40T-2

I have never installed a decoder in any of the new Athearn HO RTR SD45's or SD40T-2's.  Does anyone have any pictures or descriptions of the install?

I have some bare TCS T4X - 9 pin header plug is all, no harness type.  My guess is with the SD45 the shell comes off and the decoder simply plugs in.  The SD40T-2, can you do this by removing the DB blister or is it best to take the shell off?

Thanks!

Kato-digitrax decoder

Hi all, Has anyone ever installed Kato Digitrax FL12 Decoder? I have been following the instructions which came with a Superline Passenger Car to do so with no luck. The lights work before I put the chip in, but dont once the chips in, take it out again and they work. Therer are no instructions with the decoder. I have contacted Digitrax who told me to contact Kato , unfortunately they do not respond to emails. Can anyone advise me?
