the peavey is probably a little modern-sounding for that stuff, though it's worth a try. the screamer would be worth a try too, as would a blackmore or fireball head (if you can afford a cab too). EDIT: more likely blackmore, the fireball is probably too modern.
i guess the jcm800 is worth a look, or maybe a splawn/peters/cameron? I haven't tried these, though.
