               SOURCEONE HEALTHCARE TECHNOLOGIES EXPANDS MARKETING
             AND DISTRIBUTION RELATIONSHIP WITH DEL MEDICAL SYSTEMS


     NATIONAL DISTRIBUTION AGREEMENT EXPANDS SOURCEONE'S OFFERING TO INCLUDE
          DEL'S ENTIRE LINE, INCLUDING DIGITAL RADIOGRAPHY (DR) SYSTEMS

(MENTOR, OH and CHICAGO, IL), April 22, 2004 - SourceOne Healthcare
Technologies, Inc., the nation's leading distributor of medical imaging systems,
equipment, radiographic consumable supplies, and services to healthcare
facilities, and Del Medical Systems Group, a unit of Del Global Technologies
Corp, (Stock Symbol: DGTC), today announced both companies have signed a
contract giving SourceOne nationwide marketing, distribution and service rights
to Del's industry leading radiography and imaging systems product lines. The new
agreement also enables SourceOne to offer all of Del's digital radiography (DR)
systems.

     Building on a successful five-year relationship, SourceOne will have the
opportunity to provide its 50,000 customers, including small and large
hospitals, orthopedic centers, specialty clinics and imaging centers, access to
Del's leading medical products. Both companies believe that SourceOne's sales,
service and distribution capabilities complement Del's growth objectives.
Together, the companies believe they can more effectively serve customers of all
types throughout the country through this expanded marketing and distribution
relationship.

     "As our customers continue to make the transition from analog to digital
equipment, SourceOne is well prepared to provide them with a best-in-class line
of solutions from one company with the capacity to meet their specific needs,"
said Jerry C. Cirino, SourceOne's president and CEO. "Our expanded relationship
with Del is the most recent example of the significant strides SourceOne has
made to enhance and diversify its product portfolio."

     Del Global's President and CEO, Walter Schneider, said, "SourceOne is well
recognized for their outstanding sales and service capabilities, from their
national coverage to their response time. We believe that our expanded
relationship with SourceOne will be a mutually beneficial relationship,
including for our customers who depend on us to offer solutions that result in
reduced costs, increased productivity and improved patient care."

     Del's solution offers the latest in technology for digital radiography
imaging. The evolving cost consciousness of healthcare providers requires
diagnostic imaging services to produce high-quality images rapidly, transmit
them broadly, display them in alternate ways, and archive and retrieve them
efficiently. Del's digital radiography systems meet these demands by
streamlining diagnostic imaging sessions and providing effortless viewing,
transmission, and storage capabilities while reducing cost. For more information
