Technics 1200 MKII Quartz Speed Strobe Issue Video


Ok, this is my first post, so be nice. I am a hardcore record collector and I am slowly trying to step up in the world of sound. I don't plan to go all the way into full on "audiophillia" and funds are limited. I am just working at creating a nice solid good sounding system.

I have a Marantz 2552b and some vintage Technics SB-6060 speakers. Nothing "special" but I'm happy with them for now.

Anyhow, I recently got a pretty good deal on a used Technics 1200 MK2 Quartz and brought it in to a local hi fi repair shop. Essentially what I got back is kind of a "Frakenstein" between parts of my original TT and parts of one the shop had that had many parts in better shape. Now, I am OK with this because It looks much better and didn't have a dust cover before. Now it looks good and has a dust cover and a much nicer face plate etc...

Now, I don't know if my mind is playing tricks on me but it appears to me that the strobe dots slightly wobble back and forth slowly. I am including a link to a video that shows this. I don't seem to notice it on playback but every once in a while I think I hear fluctuations and quite frankly I'm just paranoid now that something is wrong. Below is a link to a video of the strobe. It is locked into the 0 position. This TT does have quartz lock. I am sorry for the bad video but I'd like to have other eyes inspect this and let me know what they think. I am going to bring it back to the shop and ask for a proper zero point calibration.

I am also considering changing the tone arm. Does anyone besides KAB do this and what kind of price range am I looking at? I'm already like $300 into this TT! My budget is limited but I'd like this TT to be "pimped out" to some degree...

Thanks

Mine does that too. I bought it new from KAB a couple of months ago. My guess is that it's just a defect in the way the dots were placed on the platter or something like that, and that the table runs at a constant speed. I can't hear any pitch wobbling, but I keep meaning to email KAB about it just to make sure.

When you think you're hearing pitch wobbling, are you sure it isn't because the spindle hole of the record is off-center?
I asked Kevin at KAB. He confirmed that it is only a defect in the casting of the platter, and that the speed is fine.
I figured as much, but it never hurts to ask.
