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.

A Healthy Sony Stereo Receiver
A few years ago, a friend of mine gave me an older Sony Receiver from around 1981 possibly. The unit is not a high-performance amp by any means but sounds amazing when combined with other analogue equipment such as a record player or old cassette deck. So, since it was already in working order, I decided to use it straight from there for exactly the above mentioned reasons.
However, recently, my Rock-Ola investment kind of pushed the other receiver and turntable to the sidelines for a while because the jukebox had to go in the place where the other setup was. That's okay because it gave me time to finally pull the unit apart and get a look at it.
The only obvious issues it seemed to have is crackly control knobs and some obvious dirt and debris trapped in the tuner display area. Both are not a surprise with a vintage electronic. I opened the chassis and was pleasantly surprised that every thing inside is in good shape and there are no failing caps or signs of overheat. Just what looks like a lot of sawdust.
So, I should be able to clean the controls really easily and clean the dust out of it. Not a difficult task. I did find one part of the circuits that looked a little questionable but not an issue for performance. I may put some shrink tubing on those connections. I took a picture of what I was referring to but I am not sure how well it will translate in the photo.
It is as though they realized that they needed to put two components into one space, so they bridged the parts together in a 'V' formation to make it work. I definitely found that odd as I have never seen something like that before. You would almost think it would have been better to put part of it underneath, but, whatever.
There is also a big Red plastic enclosed piece in the middle of the board with no identifiable appearance to it. It just has a model number and says it is 'Patent Pending' by Sony. I'll have to look that one up.
Well, I just started on this project out of boredom of waiting for the other parts to come in for my Rock-Ola. Besides, I don't have much else going on in the cold and dreary Canadian winters.
