if you're new to model railroading you're gonna want to see this about
power supplies so let's get started right now I'm Tom Kvichak and this is
Toms Trains and Things this channel was created to help other modelers who are
in need of guidance in pursuing their dream of building a model railroad and
today we're going to talk about power supplies or power packs or transformers
no matter what you want to call it but probably you started out with something
like this if you've got a starter set a Bachman starter set you got a power
supply like this one here you had a little wall wart that plugs into here
and you put your little plug right here going through your tracks and then
you've got a thing right two plugs right here for accessories now
in another video after this one here we're going to talk about how to change
this AC accessory into DC on your power pack if you don't have a constant DC
source on your power pack that's a future episode if this is your first
time here and you would like to see more about model railroading for beginners go
ahead and hit that subscribe button and while you're at it ding that bell and
that'll notify you whenever I have a new video coming out so let's get going
right now we have modelers that are just starting out and then there are those
like myself that have been out of the hobby for years and coming back now I
came back about five or six years ago but I stayed up with everything that was
going on but you older folks you might be familiar with a Tyco power pack ahm
model power and if you're from any European country you'd have one from
Trix a Titan but we're going to talk about some of the newer ones that are
available now now this one right this model right here isn't brand new it's
still pretty old they still make a variation of this one
right here now this one is the rail master 2400 tech 2 made by MRC this one
here has six terminals on here it has the AC accessories it has variable DC
which goes to the track and we have fixed DC not all Power Packs are like
that so basically what we're going to talk about today is the variable DC that
goes to the track power they're an accessory AC which goes to your
accessories that's what most power packs have on them even the older ones this is
an AMC that I probably got about 30 plus 40 years ago same thing with the Tyco
but this is what you see on the newer starter sets right now the Bachmann
starter sets you see this type right here we're going to go beyond the
starter transformers and take you up into tech 2 and some other ones also the
first thing you want to take into consideration when you're buying a new
power pack is how big of a layout are you going to have how many locomotives
are you going to have what are you going to use the power pack for there are
different ranges of wattages that you could find and will go on the computer
to see what you'll be looking at when you're buying a power supply now most of
the power supplies on there are from MRC and this is not a paid endorsement I'm
not getting paid by them to to talk about this but most of the power packs
that you're going to find for H 0 or n scale is going to be MRC because they
make a lot of different versions of it so let's go on a computer to see what's
going on there when you go to your local hobby shop or go online you're going to
be faced with a lot of decisions you're going to be looking at a lot of stats a
about the power supplies and I'm going to show you a few tips to take a look at
to see what is the best power supply for you for your situation so let's take a
look at some online right here now if you go online and google model railroad
DC power pack you're gonna have a lot of items that you'll see on here you'll
have a lot of different hobby shops that are online that carry them you'll even
find easy power supply for model railroad one of my videos there but
anyway I wanted to show you eBay first you're gonna find a lot of
power packs on eBay all assorted sizes shapes age now this is one that has a
lot of Lion al ones on there and I pulled up another eBay earlier that had
some vintage Tyco and AHM Power packs that I showed you in my train room
that I have but anyway be very careful when you're going on eBay to buy
anything research research research I'm gonna pull up another one here's
Fiffer hobby and if you want anything from kato go ahead to his website Fiffer
Fiffer hobby supply but let's go to some other ones that i pulled up here
we'll go over here to MRC's webpage and as you can see they have a lot of
different power supplies for your model railroad in DC they have the tech seven
the dual control one and they have the tech seven the single control one and
you can see that they're not too far away in price so now here's where you
have to pay attention because both transformers look identical the only
difference is one has one throttle one has two throttles but you have to look
at the power available on these models and the one with
one throttle has more wattage than the one with two throttles and it's just a
basic it has direction for both of them and speed controls on it no real frills
on it let's pull up the instruction manual on there and let's see what kind
of specifications Ampex 700 okay now they have 707 67 80 on here and here's a
good place to to be able to look at the total output of them now on 700 you got
20 volt amps on the 760 20 volt amps 780 20 volt amps now the 780 that has the
two throttles on it each throttle is 10 volt amps at 14.5 volt DC and then you
have 14 point 8 volt AC the only thing different on this one here is the AC is
a little bit lower and the DC is a little bit lower on each throttle so
that's another thing that you might want to take into consideration now you could
see on there even though both transformers have the same output 20
volt amps on the two throttle version those 20 volt amps are divided into each
throttle on there so actually you're getting half the power on each one of
those throttles as you would on the 760 so the 780 even though it has the two
throttles on there your power on each individual throttle is going to be a lot
less than what it is on the 760 that only has the one throttle so this is
where you have to really pay attention to what you're buying and it's not just
on the MRC ones it's on every one so go online find the instruction manual so
see what the specs are on each transformer that you are thinking of
purchasing before you buy them so you know exactly what you're getting
and then you won't be surprised once you get it so research research research
that's what's up that's what I'm going to stress all the time is find out what
you're going to buy and know exactly what it is that you are going to buy so
you could tell from that spec sheet what you're actually getting so pay attention
and do your research here are a few more that they have this is more this one
right here is more like the style almost except that they don't have the big knob
on it like I have and they have the terminals on the side of it this one
here is 18 volt amp you can see that there's quite a few on there you have to
take a look around and see what your needs are for your model railroad you
can get a lot of used power packs from people go to train shows and you'll find
a lot of them there a lot of people are going over to DCC and they have no need
for their power packs I have probably 10 power packs and a
tote over there that I don't use I just used them for demonstrations on my
videos but I bet you there's a lot of other modelers who have the same thing
that they have a lot of old power packs that are perfectly good that they were
are willing to get rid of even if you go to a trade show and talk to other
modelers there you might run into somebody that will have some that'll
sell them to you dirt cheap so take a look ask ask around see what you could
find there's a lot out there basically they're all the same they all the deuce
do the same thing you just have to see how much power they actually can handle
and that is what determines what you're going to need on your model railroad if
you're just going to want to run one locomotive at a time on
oval you're not going to need that much power honor and you can get away with a
very inexpensive power supply but if you want to run multiple trains you have
multiple ovals you have multiple blocks on there and you want to get up into
running more trains on more tracks then you're gonna have to go with the higher
wattage and maybe even a couple of power supplies the ones with the dual the ones
with the dual throttle their wattage is a little bit lower than the single
throttle so you have to take that into consideration you want to buy two power
supplies that are higher wattage or one power supply with two throttles that are
lower wattage you have to make that decision yourself I hope this helped you
out and we'll go back out into the train room to end this thing out here in
future episodes we'll be covering more on how to power your model railroad and
how to use AC and DC on your model railroad mostly DC with external power
sources so keep an eye out for those and we'll see ya
