Hello all, I have a 1967 William's Touchdown that is awaiting restoration and I was wondering, what parts are worth replacing with modern versions? for example a new power supply, I want to make it a reliable as possible and I am not worried about originality at all

Well not that far at least, gonna keep it EM for now but you know what I mean, like the internal parts like power supply are there good replacements?

#6 5 years ago

The only power supply is the transformer and they usually last forever.

The beauty of EMs is they'll still be working 100 years from now. SS and DMD games may well be obsolete due to lack of replacement ICs, transistors and other parts that are starting to already disappear...

You might invest in a new wall cord because they can get frayed. But I usually wait until it shocks me. I like that "old school" look.

#9 5 years ago

Replace any #44 bulbs with #47, this will protect the plastics and inserts.

Replace the 2 prong power cord with a 3 prong grounded.

Replace metal coil sleeves with nylon for less wear, friction and dust.

i had a cord once that was so dry rotted you could see the electrons leaking out!

Outside of the score reels. Everything else in there can be fixed with a spot welder.

yup... i think i've have read every tech thread that has come up in the em subforum for the last 2 years... not once has a problem been traced to a bad transformer...

some may look like absolute crap, but they still work...

#13 5 years ago

Get a flipper rebuild kit and some new bats if they are cracked along with the other items mentioned and you are good to go!

Wouldn't it suck if we all started finding out that the lifespan of a transformer is only 50 years?

It's not. I have older ones that still work fine.

#16 5 years ago

I knew I should have gone with 70 years, but I don't think it applies to HUO.

I know I said this before, but the first year I was out of college I saw a transformer fail at work.

My wise old engineer mentor told me I have seen the only one in my lifetime that would fail due to natural causes.

And so far after 29 years he's been right.

Transformers just don't fail unless you abuse them mercilessly

the only transformers that are worth there weight in gold is the small gottlieb system 1 xformer.
they were not fused and would blow. I know many people need them.
if you have a system 1 make sure you add a fuse asap!

#19 5 years ago

what's ironic is that they designed these machines with a relatively short lifespan in mind, yet (except for wear parts, obviously) the actual parts basically last forever...

as long as you start with a "complete" machine, you can ALWAYS make it run well... it might not be pretty, but it can be made to play 100% without a big investment...

although i do hope steve young has a succession plan in place...

i figure every transformer, both big and small, that passes through this house will outlive me... i did a "sorta restore" of a wallbox for someone, and the little transformer that was in there looked worse than any one i've ever seen*, and it worked just as good as new... i know they are basically unkillable, but i thought that one was gone... nope...

* with the exception of the one that was in the "trashcan" jukebox i foolishly dragged home one day... that big ol' sucker was melted... still sold though...

Congrats on adding an EM, PBH! Best way to keep it reliable is to play it a lot.

Do EM machines fall in the theory of where the older the car is, the easier it is to fix? I can fix my Spitfire with duct tape & a spoon easily, but a modern car, well, no.

Maybe not always easier, but most of the time cheaper.

True.

You can take almost an entire VW bug apart with a 13 mm wrench.

EM machines don't need modern parts. When the nuclear EMP is generated during the zombie apocalypse of the great third world war, all the EM machines will be up and running.

What if the nuclear EMP magnetizes all the coil stops? Then we're still screwed.

It's more fun to compete.

He's right.

EMs and all old cars that use points will still be working.

Plus any old tube radios.

So it's the crazy collectors that will have the only tech left

It would be like putting an automatic transmission in a model A Ford.

I try to keep everything original on older games, and I've never had a problem with EM switches or other parts. But I did finally give up on my Black Knight's playfield switches, since half of the switch stacks were assembled wrong from the factory. I installed microswitches - I hated to do it, but the game plays so much better now - much more reliable.

imo... anything that makes something "more reliable" is fair game... and since BK is a ss, you are allowed to do whatever you want anyway...

for example, i don't think it's the worst thing in the world to disable hold relays and coin lockouts...

I like to think of it as they have had time to finalize all the rules.

we will beat the hell out of them with hammers until we de-mag them...

It would be like converting a charcoal grill to propane.
