To the Shareholders and Board of Directors
Tridan Corp.

We have compiled the accompanying statements of assets and liabilities, and
schedules of investments in municipal obligations of Tridan Corp. as of October
31, 2004 and 2003, the related statements of operations for the six months then
ended and changes in net assets for the six months ended October 31, 2004, and
financial highlights (Note 6 to the financial statements) for each period in the
six months ended October 31, 2000 - 2004, in accordance with Statements on
Standards for Accounting and Review Services issued by the American Institute of
Certified Public Accountants.

A compilation is limited to presenting in the form of financial statements
information that is the representation of management. We have not audited or
reviewed the aforementioned financial statements and financial highlights and,
accordingly, do not express an opinion or any other form of assurance on them.

The statement of changes in net assets for the year ended April 30, 2004 was
derived from financial statements that were audited by another accounting firm
whose report dated May 15, 2004 expressed an unqualified opinion thereon, but
they have not performed any auditing procedures since that date.

We are not independent with respect to Tridan Corp.

TRIDAN CORP.

NOTES TO FINANCIAL STATEMENTS
SIX MONTHS ENDED OCTOBER 31, 2004 AND 2003

1.     Significant Accounting Policies

       The following is a summary of the significant policies followed by Tridan
       Corp. (the "Company"), a closed-end, non-diversified management
       investment company registered under the Investment Company Act of 1940,
       in the preparation of its financial statements.

       Acquisition and Valuation of Investments

       Investment transactions are accounted for on the date the securities are
       purchased/sold (trade date) and interest on securities acquired/sold is
       included in income from/to the settlement date. Investments are carried
       at amortized cost in the Company's accounting records but are shown at
       market value in the accompanying financial statements. Short-term
       investments are stated at cost, which is equivalent to market value.

       Fair values for the Company's investments in municipal obligations have
       been determined based on the bid price of the obligation, if available;
       if not available, such value is based on a yield matrix for similarly
       traded municipal obligations. Securities for which quotations are not
       readily available are valued at fair value as determined by the board of
       directors. There were no securities valued by the Board of Directors,
       which quotations were not readily available as of October 31, 2004 and
       2003.

       Amortization of Bond Premium or Discount

       In determining investment income, bond premium or discount is amortized
       on a straight-line basis over the remaining term of the obligation.

       Income Taxes

       It is the Company's policy to comply with the requirements of the
       Internal Revenue Code that are applicable to regulated investment
       companies and to distribute substantially all of its taxable income to
       its shareholders. Therefore, no income tax provision is required;
       however, the Company is subject to minimum New York State and local
       franchise taxes.

       Interest income from municipal investments are exempt from Federal and
       state income taxes.

       Cash and Cash Equivalents

       The Company considers all investments that can be liquidated on demand to
       be cash equivalents.

                                                                October 31,
                                                             2004         2003

TRIDAN CORP.

NOTES TO FINANCIAL STATEMENTS
SIX MONTHS ENDED OCTOBER 31, 2004 AND 2003

1.     Significant Accounting Policies (continued)

       The Company maintains all of its cash and cash equivalents in one
       financial institution. At times, such balances may be in excess of
       amounts insured by the Federal Deposit Insurance Corporation.

       Use of Estimates

       The preparation of financial statements in conformity with generally
       accepted accounting principles requires management to make estimates and
       assumptions that affect the reported amounts of assets and liabilities
       and disclosure of contingent assets and liabilities at the date of the
       financial statements and the reported amounts of increases and decreases
       in net assets from operations during the reporting period. Actual results
       could differ from those estimates. Significant estimates are used when
       accounting for the valuation of securities and the realization of
       investment.

       Concentration of Credit Risk

       The value of the Company's investments may be subject to possible risks
       involving, among other things, the continued creditworthiness of the
       various state and local government agencies and public financing
       authorities underlying its investments. The Company and its investment
       advisor periodically consider the credit quality of the Company's
       investments, and the Company adheres to its investment objective of
       investing only in investment grade securities.

2.     Accounts Payable and Accrued Liabilities

       Accounts payable and accrued liabilities consisted of the following at:

                                                           October 31,

              (a)    The Company utilizes the services of J.P. Morgan Investment
                     Management, Inc. ("J.P Morgan") as its investment advisor
                     and custodian for its investments. The annual advisory fee
                     is .28 of one percent of the net assets under management.
                     The fee is computed and payable quarterly, based on the
                     aggregate fair value of the net assets on the last day of
                     each fiscal quarter.

2.     Accounts Payable and Accrued Liabilities (continued)

              (b)    For the six months ending October 31, 2004 and 2003, the
                     Company incurred legal fees of approximately $37,620 and
                     $30,350, respectively, which include professional fees paid
                     to the law firm of which an officer of the Company is a
                     Member.

              (c)    For the six months ending October 31, 2004 and 2003, the
                     Company incurred audit fees of approximately $14,240 and
                     $-0-, respectively.

3.     Investment Transactions

       Purchases and sales of investments in municipal obligations (excluding
       short-term and demand investments) amounted to approximately $1,344,412
       and $1,568,400, respectively, for the six months ended October 31, 2004
       and $2,939,571 and $3,071,673, respectively, for the six months ended
       October 31, 2003.

       The U.S. Federal income tax basis of the Company's investments, at
       October 31, 2004 and 2003, was approximately $35,528,253 and $35,792,534,
       respectively, and net unrealized appreciation at October 31, 2004 and
       2003, for U.S. Federal income tax purposes was approximately $2,900,749
       and $3,094,845, respectively (gross unrealized appreciation of
       approximately $2,903,439 and $3,121,623, respectively, gross unrealized
       depreciation of approximately $2,690 and $26,818, respectively.

4.     Common Stock, Net Asset Values and Share Redemption Plan

       At October 31, 2004 and 2003, there were 6,000,000 shares of $0.02 par
       value common stock authorized of which 3,199,100 had been issued
       aggregating $63,982, and additional paid-in capital aggregating $312,787.

       The Company's share redemption plan permits "eligible shareholders" or
       their estates to have their shares redeemed upon reaching age 65 or upon
       death. Shares are redeemed at the net asset value per share as of the end
       of the Company's fiscal quarter in which the request for redemption is
       received. At October 31, 2004 and 2003, $933,992 (79,829.8026 shares),
       $858,383 (73,846.5278 shares) respectively, had been redeemed under this
       plan.

       The net asset value per share is calculated by dividing the value of all
       assets less total liabilities by the number of common shares outstanding
       at the end of the period.

       The net asset value per share and the shares outstanding were as follows:

                                                            October 31,
