Tektronix 2261 Oscilloscope manual needed

[Vorlon]

Hi,

I'm looking for the Tektronix 2261 oscilloscope manual or at least the schematics.

Thanks for any information.

Are you sure about that model number?

[Vorlon]

Positive.  It's a Y-Tektronix 2261 Oscilloscope.

Never heard of Y-Tektronix ?!?!?

A knock-off possibly?

A knock-off possibly?

Possibly.

The posted picture seem to also be shown on this page http://www.crystalradio.cn/thread-530233-1-1.html which has several more images.

That doesn't look like any 22xx I've ever seen, I don't think it is something Tektronix would allow their name to be put on.

Check out the layout of this front panel, not an exact match, but pretty close.

Tektronix has or had an Asian distributor which marketed US designs including at least some of the 22xx series of oscilloscopes with a slightly different version of their name.  The only example I have seen was from India and but it was a well known model unlike 2261 which I have never heard of.

So they were knock-offs but official knock-offs.
