celtic66, you might check with Manley, providing your serial number, to see if there are any factory upgrades.
Otherwise, if you'd like to experiment I'd agree with trying a few different tubes. I don't have experience with expensive fuses so cannot comment on those.
Of course one might ask what sort of improvements you hope to achieve before thinking about changing anything.
