We report on the progress of the development of a hybrid photomultiplier (PMT) with a high QE, red extended photocathode and a new, fast avalanche diode as electron bombarded anode with internal gain. The new PMT is intended to replace classical PMTs in the camera of the 17-m-diameter MAGIC telescope (The MAGIC telescope, the design study for the construction of a 17m diameter Cherenkov telescope for γ-astronomy above 10GeV, Max Planck Institute Report, March 1998, unpublished) for ground-based gamma-ray astronomy.
