Flipping the LP over ...

... do you keep the TT running and just yank the LP off, or do you shut the 'table off first?

Curious as to everyone's habit on that... :)
I turn the table off first.
Shut it off. If there is any grit or anything under the record when you lift it, it may scratch or score the record. Especially on a TT without a mat.
Also, I have a clamp, so I have to turn it off first, anyway.
With my table, there is a vacuum hold down and a drive switch. I shut both down and then change sides.

I have a felt mat and I must say that I leave it on throughout the entire listening period.

It depends which table I am using, I have two the rega p-25 w/ 330 ringmat gets about 10-20% of the use I leave on, the TNT JR 80-90% gets turned off because of record clamp and I am more concerned w/ rubber mat on platter may cause scratching.David
I turn it off. 2 reasons, use a clamp with my sme and the platter mat is fairly hard, so I don't want a scratch some where...
Always turn it off! No static build up, no scratches, no chance of slipping and dropping the LP and sending it toward the cartridge. No time is saved by leaving it on and besides listening to vinyl is a ritual.
I leave my spinning. I used to turn it off, but a top Linn dealer and tech I know keeps his spinning. If figure if it's OK with him, it's OK with me.
Unless you have a low-torque motor such as the ones used by Nottingham and the platter essentially stopped when you tried to hold the LP, leaving it spinning is an open invitation for disaster. Unless your timing is perfect every time, even if you lift the LP with top hands, the spinning platter will still drag the LP forward and either scractch the bottom surface or simply throw the LP entirely off the platter and even damage other delicate part of the turntable such as the stylus.

I exercised that on various tables such as VPI 19, TNT, Basis Debut and none of them worked well and I am left with a handful of damaged records. Fortunely, when the vinyl flew off the platter, they didn't hit any part of the tone arm.

The benefit is not worth the risk.
Cpdunn99, I'm with you. The salesman I bought my LP12 from had a collection of over 4,000 lp's and had owned his LP12 for almost 20 years. He knew every little nuance about the Linn. He never bothered to stop the platter. He DID teach me the correct way to retrieve it by the edges and lift ever so gently and quickly.

Thanks for posting. I don't feel like such a Philestine any more.

Care is of the essence, I suppose! But I've never met a Linn person who shut off the table. And I've never had, nor heard of, any disasters as others describe.
Since the late 70's I've never stopped my LP12 to remove an album. Never, ever have I had anything that came close to a bad event. Other turntables would likely be a problem.
I leave it spinning.
With the Linn, the felt mat is a slip device, and allows removal of the record while the platter is spinning without fear of damage. When I had my Linn, I didn't turn it off while flipping records either.

But with my new TT, this is not a good thing to do, because it doesn't have a mat. Even if I decide not to use the clamp, there is a possibility of scratching the record.
I figured Twl would show up here! Whew, now all we Linn/felt mat people can feel vindicated!
I developed a habit of flipping LP's on my LP12 without turning the motor off. It seems this works great with light / thin LP's but... I have ruined a few nice 200 gram LP's when they slipped out of my hands, fell back onto the platter and got all scratched up.

Today, I always turn off the motor before removing a record from the LP12.
Ah yes! The infamous Linn Grip, Flip, and Drop. The more adept among us can do it with 3 fingers and within 1 revolution of the 'table. All without touching or scratching the surface of grooves.
Kinsekd - how many records did you destroy before you figured it out?? :)
A couple. Thankfully nothing rare or hideously expensive.

But then, I've always been pretty fussy about how I handle my records. :o)

I've been doing it all the time and have NEVER damaged a record. I make sure not to do it "under the influence," of course!
I think TWL pointed out it depends on the table. On my rega I leave it spinning, per Rega's advise.
Cpdunn99. I guess you're lucky

Some of the 200 gram Classic Records re-releases are just about the exact same size as the LP12 platter giving you very little to grab ahold of when removing the LP from the table. It's super easy to screw up with these LPs because you almost have to get your finger nails under them to lift off the platter while spinning.

I don't have any of those 200gm (or 180gm) LPs. If I did, I guess I'd be extra careful, too! They ain't cheap!
