Cipher/hash for passphrase in PGP 7.0

Does anybody know what hash algorithm and symmetric cipher PGP v7.x uses on
private key material? I've tried many combinations of different cipher/hash
algorithms, but I can only seem to export a secret key and use it
successfully in PGP 7.x when it has *no* passphrase.

I've tried Blowfish/RIPEMD-160 (the GnuPG default), and all the combinations
of 3des, CAST, RIJNDAEL and SHA1, with no success.
