Does anyone have schematics for CT scan amps?

[dave]

specifically the 671XX or 673XX or any amp with a velocity output.

I have some old ones here, last pics in the file.

Thanks Steve,

I think i may have already seem these in the past - what i was specifically interested in, was seeing how CT does the position to velocity conversion. I assume they just differentiate the position signal to get velocity,

yes, ac couple it then differntiate. actually laser media took theirs right off the feedback differntiator and buffered it.

Any chance these laser media schematics are online?

[edit] silly question - just been looking at the schematics in your link, thanks for your reply
