'scoping tube amps
is there a definitive guide to using a 'scope with tube amps
particularly for tracking down noise

Tektronix has a very complete guide to scope usage on their site. For tube amp specifics, I'd recommend Morgan Jones's "Building Valve Amplifiers" which has a pretty thorough examination of scopes and tube circuit troubleshooting.

Take a look at "Oscilloscope Techniques" (especially chapter 7) on by book page:
