Overall the item remains in very good condition. Shipping: Charged according to location. Please feel free to contact us with any questions.

I've owned this unit for about 16 years now and it's been a solid performer until about 2 years ago when it stopped working. It was also calibrated in about and saw light daily use since then. No blown fuses and it powers up but no trace. All main board supply voltages are OK but the storage board voltages are all 0. After a bit of hemming and hawing. I kind of decided that don't have the time to fix it.

One quick thing. The A trigger pot had the polarity switch knob clumsily broken as I was moving the scope to take the pictures. It's just the knob and the pot and switch are both OK. If you're looking for one to fix up. Or for a really good parts donor, this is pretty nice and Does not come with any probes. Just what you see in the picture.

The has a 2 volume service manual, you'll need both volumes volume 2 has the schematics. There are free copies floating around, but the quality is not the best. Artek sells high quality scans and if you actually need to read the schematic, that would be a good choice. I would start by checking CRT Bias adjustment. Posts: Always starting by checking all the power supplies. Sarasir Regular Contributor Posts: 84 Country:. Hi, I was service engineer with Tek and remember this problem.

I have the manuals here I think and if you got stuck can give you some further ideas. Its basically - out of my memory many years ago - two HV ceramic capacitors and diodes around - some kind of pump circuit. Chech the diodes first and then the Cs for small leakage.
