Anyone have the Stereophile test LP
This is kind of unbelievable to me , but last night we were using the Stereophile test LP to
check to see why the output of the Grado- The Reference cartridge seemed to favor the right side of the record a little. (turns out this all depends on the record) I just need a little confirmation here cause either I need to be checked back into the nuthouse or the Stereophile people announce the left side and right side backwards. We tested from phono stage input by disconnecting one side and assuring the side we think is right is not left. We also tested the test record on an old thorens/sumiko player and it is still on the wrong side. There is no way to cross wires on the cartridge or the turntable(s) Anyone else notice this?

link.net...

Hi Phil, as I have already told you, Stereophile hasn't produced a test LP, at least not one that I am aware of since I am became editor in 1986. What is the catalog number and what is the LP's copyright date? John Atkinson Editor, Stereophile |

John:
It is at my buddies house. I did not look at it real good the other night but could swear it said stereophile real big on it as I viewed it from across the room. I will be seeing it again on Saturday and will photo it and confess if I have confused your organization with another. I bet this is another exercise in making an ass out of myself. I seem to be getting ahead of myself in that regard. If one of these goobers hooked up the cartridge backward I will probably be answering from my jail cell.

link.net... It is at my buddies house. I did not look at it real good the other night but could swear it said stereophile real big on it as I viewed it from across the room. Unless Gordon Holt produced a test LP in the 1970s but kept its existence secret, I suspect that it was the Stereo Review LP. (Or _a_ Stereo Review LP? They may have done more than one but I only have the one.) I will be seeing it again on Saturday and will photo it and confess if I have confused your organization with another. Thanks, Phil. But the real issue is whether the channels were reversed or not. Let me know what you find out. ATB --John Atkinson Editor, Stereophile |

I know that some test record may have been saying stage left instead of left which would cause this and I am not 1-- % positive that they did not say that but I am pretty sure.

Indeed it was the Stereo Review Test Record SRT-14A not anything associated with Stereophile.
My left right issue is still in question however.

Indeed, it was the Stereo Review Test Record SRT-14A,
not anything associated with Stereophile. My left-right issue is still in question however. Have you considered examing the groove under a magnifier? IIRC, the inner groove wall is the left channel. If only one channel is modulated at a time, you should have no trouble seeing which wall it is. |

On the cartridge if we brush the stylus from the center of the turntable toward the outside edge it appears to favor the right side and vice versa. I also checked panning of a few CD's that I know we have the LP for. I will first be checking these on the LP version and if CD and LP check out we will lend back the test LP to the guy who lent it to us. The guy who lent it to us says he has cut acetate on a Neuman lathe back in the day maybe he can confirm the groove information with a loop. I will keep you posted. Phil Abbate |

You could compare it to a known disc.
For instance, on my turntable the last track of side A of the RAP 10th anniversay LP has a really strident electric guitar doing short chords panned far left. I'm sure Scott could tell us if it was truly cut far left or far right. |

Okay here is my latest entry into the Humble Pie eating contest. Yes I am becoming quite
accustomed to the taste. The story starts almost a month ago. I am over at the vinyl vault with my buddy HT trying to get a handle on why the turntable seems to favor the right hand side of the audio. Did it sound like that? No we saw it that way while trying to record a couple of records to digital. Using the free VST plug-in Elemental Audio Inspector we could see it on the panorama analyzer. It also seemed to pull right on an old mono Sinatra album. Long story short two reasons for the pulling. 1) noisy tube in the right channel putting out a lot of very infrasonic noise, 2) depends on the record. In the mean time another goober brings over a test record. I forgot my glasses that night so I can barely see the huge title but think it says Stereophile but it really says Stereo Review Test Record STR 14a. Sorry John Atkinson. Last Tuesday we play the record. The announcer says left channel, sound comes out of the right. Well here is the answer. Side one track one is a channel id sweep. Side two is a crosstalk test ( or something like that) We are listening to side 2 but hell I don't know I cant read the cover 48 point type let alone the teeny track info on the cover and the label on the LP. We stick it on and it says left channel out of both sides then the signal plays out of the right track. Then the announcer says right channel and the signal plays out of the left track. I jump up and down saying the system is wired backwards. But I guess the test puts a loud signal in the channel not under test and then you are to listen to the channel under test to see if it has audible/measurable cross talk. So you hear the announcer say left channel left channel out of both speakers, then turn the ballance control all the way to the left and listen for crosstalk in the left speaker. I sure hope they have some whipped cream for my pie.
