I just picked up a garrard model 50 changer. Seems to be in great shape. Luckily the full repair manual (including part numbers) is available online. Am setting it up and trying to figure out the right stylus force to use.

The stylus is labeled ADC 90Q but I can't find any information on this. What's a good stylus force to use when in doubt? I've only setup one TT before this one and I had all the info needed then... now not so sure.

Any experience with this TT or cartridge?
