Good grief; it's only a power supply. I could turn Lionel onto an A1 manufacturer in China that could turn this in months, although maybe a year with UL. They are a magnetic shop.

Before all the naysayers jump in about Chinese manufacturing, the USA company that I work for has been using this same supplier for 25 years. Not all Chinese manufacturers are unreliable or deceitful or produce inferior product.

You still can buy new 180-Watt PowerHouses.  You just have to buy a GW-180 transformer to get one. Higher margins likely are the reason for directing the "limited" supply to GW-180 purchasers.

What, me worry? 

Nope - The GW-180s are backordered too! Just checked a half-dozen of the internet guys and nobody has any.

I don't doubt that the FCC has their knickers in a twist over something, seeing as that is their full time job.  I'm still curious what sort of radio interference a transformer and a couple op-amps could cause that requires a redesign.  Any run of the mill switching power supply has to be more of a problem than this thing, right?  Tax dollars at work.  

Happy 90th to the FCC.

You never know, Lionel might have redesigned it with a uP or something along those lines. That's the trend nowadays.

The CW-80 has a uP, so it's not out of the question...

Well, just talking here, if I were King I think I would use the protection functionality of the Legacy Powermaster in the PH-180. A hard current limit to prevent serious damage from a direct short is even better than fast acting, in my book. 

Just my $.02 worth. We will see what Lionel has in mind.

I guess the point is, the testing process is the same for what the FCC calls an "unintentional radiator" no matter what is inside the device.  As long as the thing doesn't emit interference that will disrupt licensed radio bands it should pass an inspection and easily be certified.   Now  it may be that the previous design just didn't require this testing under the rules in place, and a new design using a microprocessor does, and that would make sense.  Even in that case, however, the process to get approver is pretty straight forward.  Pay the $1,000 to a registered testing facility, get a rubber stamp.  Unless, of course, for some reason the design doesn't meet the requirements... though I see no reason a power supply run by a micro would have any trouble with this.
