Distortion and Sibilance On Technics SL1500C

Post by Jukinbadger » 27 Aug 2019 22:16

Hello, I have recently purchased a Technics SL1500C that came equipped with an Ortofon Red stylus and cartridge. I have had the TT 3 weeks and have noticed an increase in distortion expecially in inner grooves. I think I may need an alignment protractor to ensure correct placement but can anyone recommend a protractor which would be suitable for this particular TT? Any help gratefully received. Thanks in advance Ian

Hi Ian,

Since you say it has gotten worse over the three weeks, it makes me think maybe the stylus needs to be cleaned. It may have accumulated lint, dust, etc. if you haven't been using a stylus brush on it between albums. An alignment issue would be evident right from the get go.

Thank you for the feedback, much appreciated. I've cleaned the stylus and it's crystal clear but still having the same problems. I'm hoping the alignment will solve the issue. Are there any specific protractors I need to use for the Technics? Thanks again

I've always found the supplied Technics gauge to work well.

Thanks Andy, unfortunately the Sl1500C doesn’t come with one. I’m guessing I can buy one online

Yes, but you may as well download the Technics Arc protractor for free.
The Technics Overhang Gauge costs about £12

Fantastic thank you. I think I’ve solved the issue - I’ve adjusted the tone arm height and it’s sounding much better!!

@JaS Might want to move this thread to either T&T or C&P

Here's some info you can take to the bank: The Technics S-Shaped Tonearm permits exacting cartridge alignment from simply squaring the cartridge body to the headshell and setting distance from stylus to headshell tail to 52mm. No need for a protractor. And, since Technics did this for you, your problem was likely either the stylus became contaminated, or, as you apparently discovered, the VTA was not set to a height which leveled the cartridge. BTW, I have a 2M Red which was once mounted to the headshell on my SL-1210GR. I liked it, I liked it a lot; but, for greater pleasure I replaced it with a Shure V15V-MR fitted with a JICO Boron SAS.

Hi, thank you for the advice, I will take a look at the Shure and the JICO, sounds a much better set up than an upgrade to the Ortofon 2M Blue which I was about to go for!

Unfortunately the V15V is out of production for many years and if you find even a second hand one on an auction site, the price will be very high.
You have many others upgrade option from 2M Red.
This is just my opinion.

Yes, my Shure was made possible for having purchased it in the early 80’s. Go with the Ortofon 2M Blue. You only need to buy the Stylus and just insert it into the 2M Red body. This means no cartridge/headshell assembly or realignment.
