Philips crystal cartridges were notorious for turning to goo!
Was the original X3M crystal or ceramic?
Come to that, shouldn't it have been an X3H to drive a single valve amplifier?
Ceramic cartridges tend to have a lower output, anyway so, if the replacement is an equivalent to the Medium output X3M rather than a High output X3H, that could well explain the low volume.
Unfortunately, you've just missed this one ...
Jeffrey's pre-amp suggestion may well be the only solution (and certainly cheaper if you've got a few bits around)
A simple emitter follower (to present a high imedance load to the cartridge) followed by a one transistor amplifier should suffice ...
