INDEPENDENT AUDITORS' REPORT
To the Trustees and Shareholders of Fidelity Advisor Series II:
In planning and performing our audit of the financial statements of
Fidelity Advisor Strategic Income (the "Fund") (a series of
Fidelity Advisor Series II) for the year ended December 31, 1999
(on which we have issued our report dated February 11, 2000), we
considered its internal control, including control activities for
safeguarding securities, in order to determine our auditing
procedures for the purpose of expressing our opinion on the
financial statements and to comply with the requirements of Form N-
SAR, and not to provide assurance on the Fund's internal control.
The management of the Fund is responsible for establishing and
maintaining internal control. In fulfilling this responsibility,
estimates and judgments by management are required to assess the
expected benefits and related costs of controls. Generally,
controls that are relevant to an audit pertain to the entity's
objective of preparing financial statements for external purposes
that are fairly presented in conformity with generally accepted
accounting principles. Those controls include the safeguarding of
assets against unauthorized acquisition, use or disposition.
Because of inherent limitations in any internal control,
misstatements due to error or fraud may occur and not be detected.
Also, projections of any evaluation of internal control to future
periods are subject to the risk that the internal control may
become inadequate because of changes in conditions or that the
degree of compliance with policies or procedures may deteriorate.
Our consideration of the Fund's internal control would not
necessarily disclose all matters in internal control that might be
material weaknesses under standards established by the American
Institute of Certified Public Accountants. A material weakness is
a condition in which the design or operation of one or more of the
internal control components does not reduce to a relatively low
level the risk that misstatements caused by error or fraud in
amounts that would be material in relation to the financial
statements being audited may occur and not be detected within a
timely period by employees in the normal course of performing their
assigned functions. However, we noted no matters involving the
Fund's internal control and its operation, including controls for
safeguarding securities, that we consider to be material weaknesses
as defined above as of December 31, 1999.
This report is intended solely for the information and use of
management, the Board of Trustees of Fidelity Advisor Series II,
and the Securities and Exchange Commission and is not intended to
be and should not be used by anyone other than these specified
parties.
