Had a day off today {rotating shifts at the plant} , so I went and checked out a train shop a few towns away. He specialized in HO but he had evergreen supplies and was a great guy to talk to the hour I was there...wound up buying a bunch of HO flex track for my On30 and a bunch of supplies for scratchbuilding. On the way out I mentioned too bad he didn't have any O scale transformers as I really needed one...."hold up" he said and took me to a box of old O scale stuff and there inside was an old dust covered ZW....he plugged it in and the green light came on and it quietly buzzed..."give me $50 for it and it's yours". I took a chance and bought it knowing what ebay prices are for one of those...heck, given that it would cost a good $25 s/h alone left it at a $25 gamble...even at $50 I figured it was worth a shot. Got it home and sure enough - it works...all 4 outputs. Only thing is they seem to not be going all the way down to zero when they're shut off.

I'd figure they should zero out...are they supposed to? The case is solid, the markings are good and the plug is good but I will replace it anyway. Oh, max output on all 4 channels was just at 20v or slightly under at 19.8v...
With this unit I accurately checked my RMT Beep and it now works{the beep}...didn't with either of my cw80s!
Knowing what this puppy is really worth, I'm thinking of going back tomorrow and giving him my cw80s as a way of saying thanks...seems the right thing to do.
So, can any of you who own these iconic gems give me any leads on the voltage at off throttle, or any other things to watch out for.....I'm going to go clean it off!
