Exhibit 99.1

      Magnetek Completes Sale of Its Power Electronics Group to Power-One

     MENOMONEE FALLS, Wis.--(BUSINESS WIRE)--Oct. 23, 2006--Magnetek, Inc.
(NYSE:MAG) today completed the sale of its Power Electronics Group (PEG), which
manufactures embedded power supplies, to Power-One, Inc. The transaction, which
satisfied all applicable regulatory approvals and other customary closing
conditions, included payment by Power-One to Magnetek of net $68 million in cash
and assumption by Power-One of approximately $16 million of Magnetek's debt.
Stephens, Inc. acted as exclusive financial advisor to Magnetek in the
transaction.

     Magnetek will use proceeds from the divestiture of PEG in part to pay down
debt and to make a large enough cash contribution to the Company's pension trust
to substantially lower the amount of expected future contributions.

     Through the divestiture of PEG, Magnetek is making the transition from,
predominantly, a custom components manufacturer to a systems integrator, thus
changing its role from one of meeting individual customers' specifications to
one of addressing market-defined, market-wide needs. Over the past three years,
Magnetek's Power Control Systems Group, which constitutes substantially all of
the Company's remaining business, has grown at a compound annual rate of 10%,
and its gross profit margins have been above 30% of sales.

     The divestiture of PEG will also enable Magnetek to reduce selling, general
and administrative expense (SG&A) and interest expense substantially, resulting
in positive operating profit and cash flow. The Company expects that its net
operating loss carry-forwards (NOLs) will allow most of its profits and cash to
drop to the bottom line.

     If the historic performance of the Company's Power Control Systems business
is an indicator, management believes that revenues, profits and cash flow from
operations should continue to grow. The Company's objectives for calendar 2007
include:

     --   Paying off debt.

     --   Making a sufficiently large cash contribution to Magnetek's pension
          trust fund to reduce potential future contributions substantially.

     --   Reducing general and administrative expense, much of which is
          currently incurred through corporate overhead and recognition of
          pension costs, as well as interest expense that would be reduced or
          eliminated by the aforementioned debt repayment.

     --   Focusing on the Power Control Systems business, enabling Magnetek as a
          whole to realize expected gross margins of around 30% with positive
          operating profit, income and cash flow.

     --   Using the Company's $146 million of net operating loss carry-forwards
          (NOLs), most of which do not expire until after 2020, to shelter
          income from taxes.

     In sum, given three to six months following the divestiture of PEG to
consolidate operations and relocate administrative functions, management expects
Magnetek to emerge as a solidly profitable company with positive cash flow,
negligible debt and outstanding growth opportunities.
