AAVSOnet Telescope Specification

A few years ago i used an AAVSOnet telescope for observations of EE Cep for a coordinated project with John Pry. That went well.

I am currently involved with the AZ Cas Campaign and am considering submitting a proposal for use of the telescopes again. One thing very important for AZ Cas is the U band. Most CCD observers cannot observe in the U band. I seem to remember discussion about at least one sytem being able to do U band work, but I cannot find any detailed specifiations on the AAVSOnet telescopes and photometers. Can any of the systems work in the U band?
