DALLAS:
MRC packs are UNREGULATED. Your metered readings without load are erronious. When under load, the voltage will drop to it's nominal rating.
ALL UNregulated power supplies raise their voltage when not under load. My BEST MRC dropped to 3V. when under a 5 AMP LOAD*. Most today, won't even do that.

I fried the motherboard on the TT but fortunately, got excellent customer service from Walthers. They explained to me that often the listed voltage on the power pack often is not what it actually puts out. I got a voltage meter and found this powerpack was actually putting out 22V which is over the recommended limit. I replaced it with one from Miniatronics and have had no problem since. <snip>
I found that out the hard way myself, fortunately only with small lights and not a turntable. I was astouned when I put a volt meter on my power packs. At first I thought it was the meter that wasn't working right!
There ought to be a law against instant inaccurate voltage listings, even for such non-lethal amounts!!!!

Just got an e-mail from UPS saying my turntable has been delivered! Sweet.
Maybe I'll sneak out early...
I have the 90 footer. Excellent table. Easy to install and once I'd figured out the programming, it indexes accurately everytime.
Here it is with extra weathering: -

It was a good investment. No problems. After the original indexing, ours has not needed any adjustment.

Anything is possible if you do not know what you are talking about.
All right. I've ordered one. Thank you.

I have the N scale version, but I've used the HO one at my club... Way cool. Simple to wire and enjoyable to run.

The only thing I've heard is you have to keep the pit floor VERY clean.
That's a killer price Dallas has on those.
I'm thinking about getting the HO Walthers 130 foot turntable.

But before I lay out this kind of money I want some opions from those who have one. Does it run well? Is there anything special I should know? Thanks in advance.
