Help in reducing distortion from old mono records.


I listen to some old historical classical recordings now and then and I recently picked up an old London LP in excellent condition from the early to mid 50's of Ernest Ansermet conducting Stravinsky.

I usually only buy the newer reissue LPs or CDs of these historical recordings because they don't distort nearly as bad as the originals, but being a big Ansermet fan and not having this recording, and knowing that these old London monos are really hard to find in this conditon, I couldn't resist.

The Fire Bird Suite on side A plays beautifully, but the Symphony of Psalms on side b, which is a choral work, distorts badly even at lower volumes. I've noticed that voices on Choral music distorts easily on these old mono records, and to a lesser extent on old stereo ones as well. I couldn't have asked for a better copy, so I know it's not the condition of the record causing this as I've heard this problem before on other records, even unplayed, still sealed ones.

What can I do to help reduce the distortion? Any stylus recommendations? Would getting a good quality mono only cartridge help? I've never owned a really high end turntable, but I've owned Rega and Project in the past and still suffered from excessive distortion on old records.

To Johnss and Electroid,

I know that playing a record with a bad stylus can damage the grooves, but The Fire Bird suite on side 1 of the record in question plays fine. It's the choral piece on side 2 that distorts, as I stated in my thread.

I suppose it's possible only one side of this LP could have been damaged, but it seems unlikely. The Fire Bird suite was a more popular piece then the Choral one on side 2, and thus would have been more likely played than the other one. If the stylus was bad enough to cause that much damage to side 2, then that would indicate that The Fire Bird suite was probably never played at all.

I've noticed that massed Choral voices or high sopranos distort on a lot of these old records, and the problem isn't limited just to old monos but some of the first generation stereo ones as well, although to a lesser extent. Could there have been that many people out there with bad stylus' playing them?

Other than the possibility of groove damage, I've come to the conclusion that there are probably two causes for this problem.

1. The modern turntables and stylus' we use today simply cannot track these LP's properly. A turntable with a higher mass tone arm and a high quality mono cartridge may be needed, but what kind of turntable/cartridge and where do you get them?

2. That these records are just plain lousy. The technology used in the cutting of these old LPs simply wasn't good enough to record high frequencies properly, and nobody in their right mind and with ears to hear should be telling us that these things sound better than their more modern reissues, LP or CD.

What do you think? I think it's some of number one with some of number 2 thrown in also. After all, there are plenty of great sounding reissues out there taken from vintage LP's, so there must be a way to make them sound good.

I'm just trying to find out how!
Hello JDaniel13,

When you said inner groove damage did you mean inner groove distortion? That's normal to some degree on LP's as it gets closer to the end grooves but it should be barely noticeable if at all. The distortion on the Ansermet LP I'm talking about is so bad in spots on the choral piece that it sounds like it's audibly cracking up.

Also, I don't see what difference it would make whether an LP was tube-cut or not in a physical sense as far as groove damage was concerned, and weren't most LP's from the fifties tube-cut? I know that most home audio and TV's were still tube up to the early sixties.

Thanks for the info JDaniel13,

I agree that some pressings of LP's, even identical ones, can be very different from others. Just like some bottles of the same wine can be different, and just like wine, it does make it frustrating when you come across a bad one but also very rewarding and fun when you get a great one!

I recently picked up a still sealed London stereo LP of Ansermet conducting Hayden, Mozart and Schumann (not too much luck with the London/Ansermet LP's lately huh?) and it too had a couple of spots of distortion and even mistracked in one area. It was bad out of the box!

Such is the minefield that one has to occasionally put up with when buying these types of LP's. I can understand why some would rather have the newer reissue LP's, or just buy the CD. They are much more consistent.

Fortunately, I only paid $1.00 for the mono Ansermet LP and only $10.00 for the stereo one. I wouldn't risk any big bucks on LP's like this unless I trusted the dealer and he had a good return policy. At least I can still listen to the great performance of The Fire Bird suite on side 1, and if I ever find another pressing of this that plays fine all the way around, I have a NM cover to slip it into!

The problem is that I had to learn this stuff myself the hard way. There is a lot of misleading info out there from fanatically biased LP lovers, who will always blame the equipment, the amount of money one spends on it, the cleaning method used, etc., as the reason for poor sound. When in reality, the LP just sounds plain bad.
