Help can anyone give me some information on an old Tyco Model #898 Ho Hobby Transformer that I got 30+ yrs ago. it has and output of 16v 18 ac. It still works like the first day I took it out of the box but I would like to know if with the newer electric trains and electric switches if it will be enough to run them or is it too much of a transformer for them. I love this one cause it has dual controls for the trains. I just can’t seem to find any info on it anymore and my new transformer doesn’t have any info on the output. Please if there is any “Old Salts” that can help me with this I would be very thankful.
First of all, let’s get our terminology in line here. There is, by definition, no such thing as a DC transformer. Transformers are used to step AC voltages up or down depending upon the intended usage. If the device is made for model train usage, plugs into the wall (120VAC)and puts out DC voltage for the trains it is A POWER PACK. Within it’s case is a TRANSFORMER which steps the 120VAC out of the wall down to some safer voltage level. Then a RECTIFIER converts that lower AC voltage to DC. From the output of the rectifier the voltage goes to the terminals on the outside case of the device. If it also has AC terminals on the case, they are fed directly from the transformer without being rectified. If it’s an old TYCO power pack it’s not likely to be too much for the trains. Tyco never was a giant in the quality arena. You would be better off many times over by investing in a good quality unit from MRC for running your trains.
It sounds like you have a sentimental attachment to this old power pack. Nothing wrong with that. Plug it in, hook it up to the rails and see how it does. I still think a newer unit from a good manufacturer like MRC will serve you better, but you could keep the old Tyco unit around just to keep it around. A lot of modelers have similar things from their younger years on display in their layout rooms, etc.
Above all else, enjoy the hobby!
Cheers,

Welcome Aboard! Use your free pass frequently.
If you wi***o up-grade take a look at www.modelrectifier.com and click on the Icon power pack.
And you still may be able to use your tyco to power up your accessories.
Without a lecture but an answer to your question:
YES you can use the power pack. Hook the track up to the terminal that says “variable DC” or “track voltage” and operate away. If you want to e-mail me about the other terminals I’m at
Enjoy your hobby

I have those style transformers from the 1970s (I’m in my 40s).
However, consider getting an MRC “Tech” series powerpack. They’re worth it! You will notice the difference in locomotive performance right away, especially with the newer quality locomotives. The Tyco powerpacks shut down temporarily when they become too hot. [banghead]
MRC Techs will keep running trains for hours.[:)][:D][8D][;)]
The Tyco powerpacks can still be used to operate your accessories.
From an “old salt”: Hope this helps! [4:-)][tup]
If in fact that is say’s it’s a TRANSFORMER mean’s it’s AC ONLY - AND 16 volts AC. NoT for any of today’s HO except possibly MARKLIN.
Just wanted to say thank you for all the help. I never expected to get so much information in under 24 hrs. I am just getting back into this after 30 years away and having fun learning as much as I can. Teffy (BoB) I think I will if you dont mind contact you about other terminals. Thanks again John
Word of caution - buy a voltmeter. Some of the older packs could short primary windings in the AC transformer section causing them to put out MORE than their rated DC voltage. I know they USUALLY shorted secondary windings, but I also saw one putting out 36 volts.
Yes, you can use your power pack for your train today. Notice that I said train. Best to use only one loco on the pack.
One problem with older power packs is that a lot of them use a wire wound rheostat in series with one side of the output to control the voltage going to the track rather than electronics. As a result, because some of the newer locos have very efficient motors this form of voltage control might not provide enough resistance to slow or even stop the loco.
