Help? Problem With Holding The Groove On A Hot Pressing

I have had a problem holding the groove on several hot pressings and it always occurs in the same spot. I am not sure if it’s my set up or a mastering error.

I am playing a record with very strong sonics that is in Mint condition and midway through the last track it skips. When I look at the area under a strong glass I can see a very hot bass transient that almost collides with the next groove. This happened again tonight when I was playing a first pressing/orignal release of MJ’s Thiriller. It also happened on a Allman Brothers LP as well as one other.

Is this a mastering error or is my TT and cartridge not up for it? I am using a Technics 1200 with an Ortofon Blue cartridge. I have checked the setup several times with a very accurate gram scale (2.5g) and my Geodisc. Should I try for a different cartridge angle geometry?

Whas is an Ortofon Blue ? Do you mean 2M Blue ?

I have checked the setup several times with a very accurate gram scale (2.5g) ...   I have adjusted the counterweight +\- .5g and it doesn’t fix the problem.

Recommended tracking force is 1.8 g (not 2 or 2.5) for 2M Blue.
Check your stylus and slean it with Ortofon Brush, dust on the stylus is a common problem. Start with lower tracking force if your needle skip. 

Also try without anti-skating (and don't use more that the tracking force)

 I have checked the setup several times with a very accurate gram scale (2.5g) and my Geodisc.

To setup any cartridge in Technics SL1200 you don't need a Geo Dics, this tonearm has its own geometry , very close to Stevenson. All you need is a while plastic overhand gauge that comes with your turntable. If the stylus is under the mark your geometry is fine for this particular arm.
