You did replace the coupling caps, didn't you? The electrolytics would take care of power supply hum and output coupling, but most often, it's the interstage coupling and bypass caps (.01 - .22uf) that go bad, yielding a low output. Do you get a loud hum when touching the leads to the cartridge? With the volume at mid range, you should get a loud hum (60hz induced by your body). If you don't get the hum, a new cartridge won't solve your problem.

Cheers,
