Exhibit 99.1

        Magnetek to Announce Fiscal 2005 Year-End Results on August 25th;
  Company Updates Fourth Quarter Guidance, Comments on Discontinued Operations

    LOS ANGELES--(BUSINESS WIRE)--July 8, 2005--Magnetek, Inc.
(NYSE:MAG) will announce the results of its 2005 fiscal year, which
ended on July 3 (a), before trading commences on the New York Stock
Exchange on Thursday, August 25, 2005. A conference call with
management regarding the results will follow at 11:00 a.m. Eastern
time. The conference call will be carried live and replayed on
Magnetek's website: www.magnetek.com .
    Today, the Company provided further guidance as to the fourth
quarter of fiscal 2005. Fourth-quarter 2005 earnings from continuing
operations are expected to be near breakeven on revenues of $57 to $58
million, versus a loss of 7 cents a share on $57.0 million in revenues
in the third quarter of FY `05. Including results of discontinued
operations, the Company expects to report a loss of 5 to 7 cents a
share, versus a loss of 86 cents per share in the third quarter of FY
2005.
    Most of the third-quarter loss from discontinued operations ($22.5
million or 77 cents per share) reflects the booking of an arbitration
award reported by Magnetek on May 4, 2005. Although the Company is
contesting this award in Federal Court, it is also holding settlement
discussions and preparing to pay the award, if necessary, through debt
refinancing and the sale of assets unrelated to its long-term
power-control technology growth strategy. Court briefings are
scheduled to be completed on July 15, 2005 with a decision expected
thereafter.
    Magnetek, Inc. manufactures power control products and systems for
communications, data processing, industrial automation, consumer
products, mass transit, alternative energy, utility grid monitoring
and other applications requiring highly reliable, precise,
energy-efficient power. The Company operates manufacturing and
research facilities in North America, Europe and China, and reported
total revenue of $243 million for its 2004 fiscal year, ended on June
27 (a), 2004.

    (a) Magnetek's fiscal year ends on the Sunday nearest June 30.
