We bet you haven't seen one of these particular systems in a decade or five! The Heathkit IO-103 is a storage oscilloscope. An oscilloscope is basically a testing instrument that graphically displays the volage wave form of one or more signals. The IO-103 is a flexible system that can be used to observe or measure all types of electrical and electronic waveforms within its listed specifications, from relatively simple sine and square waves to complex pulse and composite signals.

The model 10-103 uses four printed circuit boards to minimize point-to-point wiring and reduce construction time. It has good display stability because both amplifiers and the sweep circuit power supplies are zener regulated. This system currently has no display and needs a full calibration, but for the right person who wants to give this amazing system the service and care it needs, it can become the perfect oscilloscope!

My Sony 400 disc player stopped working. I watched YouTube videos and came across this website. Since 90% of failures are the belts I decided to try to fix it myself with the help of the video. It was the belts and after installing them it works great again. I received the belts really quickly and with no prior knowledge took the case off with help from the video and installed the belts myself. So happy to have my player working again. I will always contact Spencertified for my parts and repair needs. Thanks so much. Try them, you won't be disappointed.

Spencer and Amy helped us find 40 or so speakers to build a wall out of them at a restaurant and were super helpful finding and loading up all of the speakers. The wall turned out great and would definitely recommend them for anything sound!

REALLY! It was cool to do business with honest people who listened and gave me just what I was looking for. I asked a lot of questions about equipment and was shown different options, and, different prices, straight forward and honest.

Spencer was super helpful and knowledgeable when I visit him. I experienced a slight issue with some hardware and he was more than willing to make it right. As a nice gesture he gave me a slight upgrade to the equipment I was purchasing. He’s very reasonable and enjoyable to work with! Highly recommend!
