This is truly an amazing instrument. It is nearly in mint condition. Please review all the pics... this is as clean as it gets. I wish I could post more pics of the inside because it is just as clean.The best I can surmise is that the unit failed sometime way back and the unit was put into storage. It must have been in a controlled environment for a very long time as there is no signs of any oxidation anywhere. The inside is as clean as the outside. There isn't even any dust on the first anode lead (high-voltage) which ALWAYS collects dust. Even the gray trigger switches which normally oxidize and get a dusty gray color, look like they are brand-new.
The controls are smooth, tight, noise and jitter-free. As can also be seen buy the pics, it is calibrated and has a very bright, well-focused display. The storage functions are excellent. These analog scopes have a tendency to "wear-out" over time and usage... but the variable persistence and fast store functions are solid. This can capture very fast events with a writing speed of 1350cm/us. It also has a waveform save mode which will hold a waveform indefinitely. The DM44 works just fine as well.
The case has a few scuffs and small paint scratches... but very few... and the feet show signs of some wear... but are intact. The pouch still contains the ORIGINAL manual along with the small parts Tek provides with new instruments. It does not come with any probes.
This may be the only scope that I truly regret selling in the 45 years I've been repairing scopes. Even when I worked at Tek in the mid '70's, we would rarely see an instrument this clean. This is a true find for a collector of old test equipment... but it is perfect for everyday bench use as well. If interested in seeing more pics of the inside, or anything, just ask.
The last 3 pics are of waveforms to show functionality. The first is an AM waveform, the 2nd is an A intensified by B waveform, and the last is a 10KHz sine wave showing the level of calibration and also the graticule illumination. I modified it using white LED's instead of the wimpy incandescents Tek uses. Much more uniform and brighter.
Don't hesitate to ask questions about any part of this listing. Be glad to help.
