You'd test a pickup cartridge for output using a vacuum tube voltmeter on the AC scale. You'll need to get about 2 volts peak out of it before it can drive the 6A7 to full modulation. It's hard to say what the piezo element was that the guy put in your cartridge. M any of the ceramic pickup cartridges don't have much voltage output, and that may be what they guy used to put in your cartridge.
You may have a problem now, because if it's a low output crystal and you never specified high output, you could be stuck with what you have.
