They never match perfectly which is OK. I shoot for averages between 10 and 8. You lower the resonance frequency by adding weight to the head shell and raise it by subtracting weight. You can get head shell weights that fit under the cartridge or you can add nuts to the screws etc. Subtracting weight is a bit more difficult. Get out the drill. Warning, if you get down to 3 Hz record warps will send the tone arm skywards! Use the anti skate test track to set the anti skate. If you lift the anti skate weight while playing that track you will notice all the distortion go to one side. If you add too much weight the distortion will go to the other side. You adjust it until the distortion is the same and minimal in both channels.
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?
