A friend of mine picked up this little tabletop pinball toy manufactured by Marx Toys. I figure that it is probably from the late 70's to early 80's, just based on the 'Atari-Like' font they used on the front of the box. However, it is not affiliated with 'Atari' in any way from what I can tell.
He asked me to look at it as it wasn't working all that well considering it's age. So, I cracked it open on my home bench and discovered the simplicity of the toy. Basically, there is a metal ball bearing inside the table that is fired around like a real pinball machine. The bumpers on the surface have two contacts in them, one is a sprint to bounce the ball and the other contact is on the bottom under the spring. So, when the ball hits the contacts, it triggers an electromagnet inside that strikes a bell and also moves a mechanical points counter. Basically, that's all there is to it.
The flippers are moved manually with hand-grip levers that you squeeze. The ball launcher is also mechanical and works from the center of the table.
The ball and the contacts have become somewhat corroded over the years so the ball striking the contacts does not always trigger the electromagnet. I was going to pop the table open to clean up the contacts but found that the table is actually assembled in such a way that you would have to break it permanently to get it open. So, unfortunately, this is one old vintage device that is better off not being messed with.
So, I basically just cleaned it up and oiled a small lever connected to the magnet and bell. The bell is louder now but the contacts are still flaky. That's okay, it isn't the real deal and I doubt the owner is very concerned about that anyway. He just thought it was a neat toy from the days of his childhood.
It would make a better decoration on a shelf or hung on the wall I think than anything else.

It's exciting that I have managed to clean up my Rock-Ola. After replacing a few obvious problem components and lubricating some easy to access mechanics, the machine seems to be in amazing working order.
I put some good favourite tunes into it and we set it up in our front office. So, intimate enough that if you turn it down, you can privately enjoy some tunes or that it can also be loud enough to be heard across the main floor of the house.
I think that in the not too distant future, I will actually strip the machine right down to be repainted and to grease and oil even the things I didn't get the first time. But for now, it's working really good so I will just let the family enjoy it for a while.
A good friend of mine has been coaxing me to make some offers on more machines that have been appearing online so I can start restoring them and flipping them. He is interested in being a silent partner, so to speak, and to help me out financially if I am serious about making this kind of thing into a more professional hobby. It's something I have to think about as I don't really have the best facilities to work on these things or to store them. My basement is ideal and where my main workshop is, but hauling those machines up and down the stairs could be asking for disaster.
I do have a garage, mind you, but it is small and not exactly secure. I will have to think on the idea a bit more. My heart tells me 'Yes' but my brain tells me to keep my feet on the ground.
Well, I cleaned out the Sony receiver. Mostly just what looked like a bit of sawdust material throughout the inside of it. There was nothing wrong with any of the components so that was a plus. So, I cleaned it out and greased the tuning controls as they were really dried out. I also pulled the tuner display off and cleaned out all the dust that was in behind it.
Then I sprayed contact cleaner into all of the control knobs and switches to get rid of the crackly noises they were making. After making sure the controls were completely dried out after a couple of days, I plugged it in and took it for a test drive. Still sounds amazing. Even better now that the controls have stopped crackling.
A little furniture polish on the wood cover and it looks really good. I might keep it around for my workshop to test audio equipment that I am working on (turntables and such) or just use the radio to keep me company while I work on other things.
