Thanks! The credit card trick worked like magic. You're right, no access from below the platter, looks like I'll need to get a little more adventurous and get under the cover near the arm.

Hello, I'm trying to adjust the anti-skate on my 3404 - the service manual clearly shows what's required, but I'm just not sure how to get to that adjustment. I'm not even sure how to remove the platter?! Gentle pulls upward yield no result, and I'm nervous to use too much force on any piece of this old turntable. Could anyone here
