That's why I mentioned the other DIY options, they are more current and the parts are definitely available, in case the Booster3 parts aren't.

Hi Randy,
I enjoy building my own stuff. The purpose in locating the article is to track down the parts to see if they are still available. There are only 3 dip packages on the board, The rest are discrete components like transistors, resistors and diodes.
The original board is a double sided board, which I wouldn't attempt to duplicate, however, I do make single sided boards using the photo-sensitive process. There aren't that many jumpers required for the second side.
I can't think of a reason why there would be a propriatory chip on this board since all that is needed is to provide a filtered power supply, mixer and amplifier. The additional circuitry is for short detection and optional meter insertion.

If you can still get the parts. Tam Valley has a simple generic booster that will work on any system, Hans DeLoof has a circuit for a similar one (he has 3 variations, 2 use Loconet, one is generic for any system). Rob Paisley also has two, one is 3 amps, the other is 1 amp.
Thanks Robert,
Now, all I have to do is go through my archives and find the article. I am going to try and breadboard one of the booster3s.
The booster was in the March 1997 issue. The whole series of articles ran from February through July, starting with the command station then the booster.
Does anyone remember what issue of Model Railroader Keith Gutierrez put his construction articles for EasyDCC? I am looking for the parts list for their Booster3.
Thanks,
