Dave, There are a wide range of scopes in the 400 series. The 465 and 475 share a common design and have many parts in common. The main difference between them is about 100 MHz in bandwidth :-P Here

Real stunners!!!

From Tim P (UK) From what I can see through the layer of crud, the red badge near the calibrator knob is the logo of Livingston Laboratories. LL were a high-end Lab instrument hire company in the UK.

The latest is that a kind soul on EEVblog has decided to send me two of those Attn. Cap blocks from his old collection of parts. I have to pay only the postage. Such nice guys are still around! Should

I had no idea: I thought the 475 was the one with the vertical input to the right of the screen. I had to go and check myself - have I been calling my scopes 465 by mistake!? No, they really do look

I checked my working scope this morning. I wish we could do inline pictures. I reviewed my tear down pictures and found that I had a shot of the DTP knob before I took it off, and am 99% certain that

Colin, Oh, I had expected some kind of calibration process, but it's just a bunch of constant offsets for different models. I see that I am lucky to only be concerned with a model that is always set
