I finally decide to order one for the upcoming Christmas season and I see the 6-22983 has been replaced with the newer 6-85226 in the latest catalog. Lionel must have had a reason to change the part number. Yet the combo 6-37947 that has the throttle and brick, has not changed part number, so are they going to ship the old version with it, while they last, and just switch to the new version and leave the part number alone?

With the newer one being back-ordered in most shops, people must want the newer version, if they can get it.

Anyone know what is the difference? 

Thanks

It would be nice if Lionel (or someone) would describe the upgrades/changes/differences (if any), I'd like to know too. There was talk of changes being made to the coming batch of 6-22983s a couple of years ago when they were out of stock for so long. The part number never changed when they finally became available, so I guess those were the same items?

I have a couple of the newer 6-22983s, from after the long wait. From the outside they look identical. I want to one day take the covers off and compare both to see if I can determine any inner differences. That's on a long list of to do's, maybe one of these says...I did order the proper triangle screw driver for them, hope it fits as it's supposed to. 

Could it be that since the PH-180 only makes up half of the 6-37947 (GW-180) they left the part numbers the same? I'm curious here as well.

Can someone explain what CJACK means when he wrote -- One thing they could have done is protect the LED in the switch from the "other" half cycle of the AC input voltage.

I am also confused - what is the GW180??  From the Lionel catalog description, the PowerHouse power supply "provides overcurrent protection in the event of a short circuit"   Are they saying that the PowerHouse is nothing more than a circuit breaker??

Please help, I am a 'newbie' to all this electronic stuff, thanks ---   

The new PH180 has a switch in the output connector that requires you have a pin in the mating connector to enable power flow.  I also suspect the actual circuit for the breaker is quite different since it's been a long time since the old one was designed, and it's all analog circuitry.  I've yet to see anyone pull one apart and take a shot of the PCB, and all my PH180's are the older 6-22983 model.  I know the relay is obsolete, but the other parts are available.

Here's the schematic of the original PowerHouse 180

I just ordered 4 180-watt bricks; 3 from one source and 1 from another. The 3 I bought together are # 6-85226 and one of them is the older #6-22983. All are brand-new. Would there be any issues with using the 1 older model with the 3 new ones? Also, I put my meter on it and it's putting out 24 volts instead of the 18 volts the 6-85226 bricks are putting out.

Can anyone note their experience with the Z-4000?  I just purchased one for my new layout and now have some concern if they are dependable and work as expected.  I’m new to 3R railroading after 25 years in G scale, and am learning everything.  Thanks.

The Z4000 has been on the market for decades and has a good track record. However, just like any other electronic device, internal components can still fail. I bought 2 brand-new Z4000s in 2018 and have been very happy with them, other than the fact that the circuit breakers are slow to trip. The concern many of us have, with the news of MTH's closure, is the availability of parts in the future.  Time will tell how that works out. Welcome to the world of 3-rail O-Gauge!!
