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?

You have the answer. So why continue beating the dead horse? Especially when said horse is a red herring. As in off the beaten track. As in you were on the right track so why go off it?

You have the answer. You had too much anti-skate. Backing off eliminated the problem. Therefore its related to skating. Nothing to do with mastering. 

Which by the way, never did make any sense. Mastering is what they do with the recording getting it into its final form. All the stuff you're talking about has more to do with cutting than mastering. Which not that that's not an interesting subject. Peter Gabriel gave a lot of thought to song sequence on his album So, which for artistic and emotional reasons ought to have saved In Your Eyes for last, but he knew the bass would be a problem that close to the end of a LP which is why we have it track one side two. So these things matter, just not quite the way you're saying.

Now back to your maladjusted anti-skate. The correct amount of anti-skate varies constantly depending on tracking force, angle, and degree of groove modulation. A smooth or lightly modulated groove with low tracking force requires very little anti-skate. A highly modulated groove with greater tracking force requires more anti-skate. (Modulated btw is the correct term. "Hot" is both wrong in meaning and unfortunately already taken as in trademarked https://www.better-records.com/ )

So normally the highly modulated bass that caused your skipping would have called for more anti-skate. That it didn't tells me your anti-skate was set way too high. Way too high.
