Message from the President of MRC

To our valued customers

We have been informed that there may be some issues with the new Atlas Genset locomotives when used with our MRC Tech 6 Sound Controller 2.0.

At MRC, We take claims very seriously. Every MRC product goes through thorough and exhaustive testing; conducted both in-house and by 3rd parties. We do this to ensure our products meet the highest quality standards, and are free of defects in design, workmanship, and operation before the product goes to market. The Tech 6 is certainly no exception.

Thanks for the update and the new information.

Can we get more technical here? What is the problem that has been observed, and what are the circumstances under which it shows up? I’m assuming it’s a feature specific to the MRC supply which triggered the original problem that was reported.

By the way, I run DCC, and the Genset is completely out of my era, so my interest is purely for the sake of the engineering involved. But, I’m a lifelong geek, with a slide rule in my desk drawer to prove it, so please, give us all the tech-talk and analyzer images you’ve got.

Asterisk and underlining are mine. Seems they feel the problem might be resident in the Genset.

Agree selector. sounds like MRC is punting, saying Atlas has a problem. If their tests are valid, they could be right.

It almost has to be anyway, since none of the other locos done by Atlas or anyone else have reported frying on the Tech 6.

One of the possibilities noted in the forums is the fact that Atlas placed two 50uf caps wired in series across the motor leads. Many are suggesting to cut these out. Mine are cut out and the loco runs smoothe as a baby’s bottom.
