         Re:  Advanta Mortgage Conduit Services, Inc. and
         Advanta Conduit Receivables Inc.,  Mortgage Loan
         Asset-Backed Securities

Gentlemen:

         We have acted as counsel to Advanta Mortgage Conduit Services, Inc.
(the "Sponsor") and Advanta Conduit Receivables Inc.  (the "Transferor,"
together with the Sponsor, the "Registrants") in connection with the
preparation and filing of a registration statement on Form S-3 (the
"Registration Statement") being filed today with the Securities and Exchange
Commission pursuant to the Securities Act of 1933, as amended (the "Act"), in
respect of Mortgage Loan Asset-Backed Securities ("Securities") which the
Registrants plan to offer in series.

         Our advice formed the basis for the description of federal income tax
consequences appearing under the heading "Certain Federal Income Tax
Consequences" in the prospectus contained in the Registration Statement.  Such
description does not purport to discuss all possible federal income tax
consequences of an investment in Securities, but with respect to those tax
consequences which are discussed in our opinion, the description is accurate.

         We hereby consent to the filing of this letter as an Exhibit to the
Registration Statement and to the reference to Dewey Ballantine LLP in the
Registration Statement and related prospectus under the heading "Certain
Federal Income Tax Consequences."


                           Very truly yours,
                           /s/ DEWEY BALLANTINE LLP
                           ------------------------
