Dear Shareholder:

      I am pleased to provide this annual report of Tridan Corp. for the fiscal

that period and for the corresponding period in 2005. Also enclosed are the

      A schedule of the company's portfolio holdings at April 30, 2006,
consisting entirely of municipal obligations, is included in the financial
report. The company invests exclusively in non-voting securities. The company
files its complete schedule of portfolio holdings with the Securities and
Exchange Commission for the first and third quarters of each fiscal year on Form
N-Q. The company's Forms N-Q are available on the Commission's website at
http://www.sec.gov. They may be reviewed and copied at the Commission's Public
Reference Room in Washington D.C., and information on the operation of the
Public Reference Room may be obtained by calling 1-800-SEC-0330.

      The net asset value per share at April 30, 2006 was $12.04, compared with
$12.51 at April 30, 2005. Net investment income per share was $.43 for the year
ended April 30, 2006, compared with $.43 for the year ended April 30, 2005.
Distributions to shareholders amounted to $.47 per share for fiscal 2006,
compared to $.48 for fiscal 2005.

      At the company's last annual meeting on June 21, 2005, the reappointment
of Leslie Sufrin & Company, P.C. (which has since merged into and become a part
of Weiser LLP) as the company's auditors for the fiscal year ending April 30,
2006 was ratified by the shareholders as follows:

      The following Tables A and B set forth information concerning the
directors, and Table C sets forth information concerning non-director officers

Pelton) are "interested persons" as defined in Section 2(a)19 of the Investment
Company Act of 1940, and the Table B directors (Messrs. Kramer, Negin and
Stoever) are not. Peter Goodman is an "interested person" because he is an
officer and holder of more than 5% of the shares of the company, Mark Goodman
because he is Peter Goodman's son, and Warren Pelton because he is an officer of
the company.

             Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors
Tridan Corp.

We have audited the  accompanying  statement of assets and liabilities of Tridan
Corp.  (the  "Company"),  including  the  schedule of  investments  in municipal
obligations,  as of April 30, 2006, and the related statements of operations and
changes in net assets for the year then ended and the financial highlights (Note
7) for the year then ended. These financial  statements and financial highlights
are the  responsibility of the Company's  management.  Our  responsibility is to
express an opinion on these financial  statements and financial highlights based
on our audit.

We conducted  our audit in accordance  with the standards of the Public  Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement.  An audit
includes  examining,  on a test  basis,  evidence  supporting  the  amounts  and
disclosures in the financial statements. Our procedures included confirmation of
securities owned, as of April 30, 2006, by correspondence with the custodian. An
audit also includes  assessing the accounting  principles  used and  significant
estimates  made by  management,  as well as  evaluating  the  overall  financial
statement  presentation.  We believe that our audit provides a reasonable  basis
for our opinion.

In our opinion,  the financial  statements and the financial highlights referred
to above present fairly,  in all material  respects,  the financial  position of
Tridan Corp. as of April 30, 2006, and the results of its operations, changes in
net assets and financial  highlights for the year then ended, in conformity with
accounting principles generally accepted in the United States of America.

1.    Significant accounting policies

      The following is a summary of the significant accounting 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. Short-term investments are
      stated at cost, which is equivalent to fair value.

      Fair values for the Company's  investments in municipal  obligations  have
      been determined  based on the bid price of the obligation.  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,  for which quotations were not readily  available,
      as of April 30, 2006 and 2005.

      Amortization of bond premium or discount

      In determining investment income, bond premiums or discounts are amortized
      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.

      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.

      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
      disclosures  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 in
      determining the fair value of investments.

      Concentration of credit risk

      The Company's financial  instruments that are exposed to concentrations of
      credit  risk  consist   primarily  of  cash  and  cash   equivalents   and
      investments.  The  Company  maintains  all of its cash on  deposit  in one
      financial institution.  At times, such amounts on deposit may be in excess
      of amounts insured by the Federal Deposit Insurance Corporation. The value
      of the Company's  investments may be subject to possible risks  involving,
      among other things,  the continued credit  worthiness 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.

4.    Investment transactions

      Purchases and sales of  investments  in municipal  obligations  (excluding
      short-term and demand  investments)  amounted to approximately  $5,172,000

5.    Common stock, share redemption plan and net asset values

      At April 30, 2006 and 2005, there were 6,000,000 shares of $0.02 par value
      common stock  authorized of which  3,199,100 had been issued,  aggregating

      The Company has a share redemption plan applicable to approximately 52,000
      shares and 55,000 shares,  respectively,  of outstanding  common stock, at
      April 30, 2006 and 2005. The plan permits  eligible  shareholders or their
      estates to have their shares  redeemed by the Company upon reaching age 65
      or upon death. Shares are redeemed at the net asset value per share, based
      on fair value, as of the end of the Company's  fiscal quarter in which the
      request for redemption is received.  At April 30, 2006 and 2005,  $984,115

      been redeemed under this plan and are held in treasury.

      The net asset value per share is calculated by dividing the aggregate fair
      value of all assets less the aggregate  fair value of all  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:

                         POTENTIAL CONFLICTS OF INTEREST

As an investment advisor, J.P. Morgan Investment Management Inc. has a fiduciary
obligation to act in the best interests of its clients, and to avoid any
conflicts of interest. As such, JPMorgan Asset Management has adopted a
"Safeguard Policy" designed to prevent its investment management process from
being influenced by clients of other parts of the firm, as well as by clients of
the investment management business. Communications between personnel outside the
investment management business and investment professionals within J.P. Morgan
Investment Management Inc. are strictly limited.

JPMIM has adopted policies and procedures that are designed to ensure that
transactions undertaken with affiliates are allowable under current law and
client guidelines and that any potential conflicts of interest are recognized
and appropriately addressed.



JPMIM also has policies and procedures to monitor personal trading activities of
its employees and certain members of their immediate families and any person to
whose support the employee significantly contributes. The policies and
procedures are generally intended to comply with the JPMIM's Code of Ethics.

                         PORTFOLIO MANAGER COMPENSATION

The Adviser's portfolio managers participate in a competitive compensation
program that is designed to attract and retain outstanding people and closely
link the performance of investment professionals to client investment
objectives. The total compensation program includes a base salary fixed from
year to year and a variable bonus consisting of cash incentives and restricted
stock and, in some cases, mandatory deferred compensation. These elements
reflect individual performance and the performance of the Adviser's business as
a whole.

Each portfolio manager's performance is formally evaluated annually based on a
variety of factors including the aggregate size and blended performance of the
portfolios such portfolio manager manages. Individual contribution relative to
client goals carries the highest impact. Portfolio manager compensation is
primarily driven by meeting or exceeding clients' risk and return objectives,
relative performance to competitors or competitive indices and compliance with
firm policies and regulatory requirements. In evaluating each portfolio
manager's performance with respect to the mutual funds he or she manages, the
funds' pre-tax performance is compared to the appropriate market peer group and
to each fund's benchmark index listed in the fund's prospectus over one, three
and five year periods (or such shorter time as the portfolio manager has managed
the fund). Investment performance is generally more heavily weighted to the
long-term.

Stock awards are granted as part of an employee's annual performance bonus and
comprise from 0% to 35% of a portfolio manager's total award. As the level of
incentive compensation increases, the percentage of compensation awarded in
restricted stock also increases. Certain investment professionals may also be
subject to a mandatory deferral of a portion of their compensation into
proprietary mutual funds based on long-term sustained investment performance.
