speed

First of all: I’m extremely detail-oriented and tend to obsess over my turntable. While closely observing the platter on my deck, I’ve noticed a slight oscillation in the strobe dots. It’s almost imperceptible and I don’t hear anything unusual in the sound. It might be due to wear on the...

Hello all, I have a nice SL-1700 that has developed a speed issue after about 30 minutes of use. I can usually get through one side of an LP and a song or two on the other side, then the speed slowly ramps up. Looking at some of the previous threads about issues with this model, I cleaned all...

Hi All, I have an Oracle 1 turntable, serial # 3954. It is running very slow and there is no change between 33 & 45 when I press the speed control buttons, in the front. The motor seems weak, the RPM seems consistent, no fluctuation? I'm pretty mechanical, any suggestions where to look/start...

Hi. I have had this tt from new. It’s been in its box for a few years and was sporadically used during the cd era. I want to use it again as I still have a lot of vinyl, some emotional. It works, almost. Sound ok (but, below…), mechanism fine. It’s direct drive, uni-torque. Problem: uneven...

I am cleaning up a Numark TT200 and experiencing some issues with the spoed controls. Seems pretty straight forward: press the button that indicates the desired speed (33rpm or 45rpm) or press both for 78rpm. When I press 33 and/or the red light indicates that 33rpm is selected the platter...

I've recently got a Sony PS-X4. The speed was floating! I cleaned all the potentiometers and adjusted the speed to 33.33 rpm without the jumper wire between the pins 8-9 according to the service manual. I untied the jumper wire, however, I couldn’t tie it back I soldered two small...

Hi all, My pre-pandemic purchase was a Thorens TD165; this was right when it was more common than not to believe it would be a month-long thing and we'd all move on. Alas! So, it became a project turntable. I even had designs to learn how to solder (I never did). And after purchasing a bunch...

Hello everyone! I have a Realistic Lab-270 turntable. I’m setting it up in a new house and noticed the speed sounded slow. The RPM Wow app showed the speed as 32.57. I played my guitar along with Dokken’s “unchain the night,” and it was perfectly in key as Eb. But the song is the key of E. I...

Well, at least I know I'm not going crazy. I was just listening to and enjoying Beethoven's Sonata No. 1, Op.12 in D for violin and piano, Isaac Stern and Eugene Istomin, on CBS Masterworks I2M 39680... and yet it just didn't sound like it was in D... and I KNOW that sonata.. I've played it on...

Hi, Looking for advice on fixing this issue. Playback speed is fine until the tape has played about 3/4, then the speed starts fluctuating, as if it can't cope with the weight of tape on the take-up spool. I've cleaned and lubricated the idler wheels, and also disconnected and tested the motor...

Hello all, My TT has been rock solid for a long time. Tonight however the speed was off. I tried adjusting the pitch dial, but even when turned all the way right(?) it’s still a little too fast and the strobe is walking slowly to the left. It stays locked in at this speed, but it’s too fast...

TT is a Realistic Lab-290. It was playing a bit fast so I went to adjust it. As I toyed with it some hardware broke off (pictures attached). Is this something I can fix or do I need a technician on this?

Hello all, I'm trying to fix a Sansui turtable, last thing I had to fix was the platter rotation that was not completely stable, I had 0.22 speed variation, to make a long story short the problem was in the tachometric PCB alignment, after some work and some unsuccessful component substitution I...

Hi all I've re-found my old MB.14 and had to replace the belt as the old had rotted away. (AND aqcuire a pre-amp, but that irrelevant here and now.) Everything is clean and tidy and works, but the speed control is weird and I can't figure out why... Everything seems so damn simple and...

Hey, I’m a newbie here. I recently purchased an old PL-50. It works BUT, I have the too fast speed issue. I’ve ordered 2 belts so far. The second one being the .025 thinner one. She’s still playing tooo fast. After looking closer, each of the belts start out fine but within a few seconds ride up...

Hello everyone, I’m posting after having sifted through previous posts and not finding one that fits my specific case. I acquired a Realistic LAB 440 TT earlier this year which was supposed to be functioning perfectly. I found upon setting it up that I right away got this odd speed problem -...

Hello. New member here. So I cleaned up a Dual 1229 that was actually gifted to me and the motor seems to be a touch slow. I removed almost, if not all, the old grease and replaced it, took the motor apart to re-oil the felt, re-glued the strobe ring under the platter as well as a lot of...

All three of the vintage turntables I've owned over the past 5 years (1 belt drive and 2 DDs) have had speed issues, and I have never been able to get the strobes locked in and perfectly still. Using the RPM phone app with the strobe at its most stable always reveals the platter is moving a...

Hi guys, I have H/K CD-401 never paid attention to it's speed, but recently acquired speed test tape from duplication.ca and turned out to be that its about 7% slower ! I used Tek 2252 scope with Frequency meter function as well as HP/Agilent 5315A Universal Counter to double check on replay...

Hi all! First time posting here.. I bought a mint Hitachi HT-550 from an state sale a decade ago and have used it occasional ever since. I've been buying more vinyl lately and need a reliable unit. Also, Its such a beautiful turntable. Over the years, the speed began to slow for a second, then...

Hello all, I have a Revox turntable in working condition, I've replaced all the capacitors, diode bridges and whatever is reasonable in such an old machine, the regulators I remember, in practice all the components that Revox experts recommends to change. The speed is OK, from time to time...

My trusty & beloved SR-838 appears to have developed a speed issue. It seems to slow down about every three seconds before recovering. I have tried moving the fine pitch control to address, but the problem persists. Has someone here encountered this and the protocols & triage for fixing for it...

I never understood what people meant by this. The turntable turns the record that's it right? So if you use a decent turntable and the same arm and cartridge shouldn't the sound always be about the same even when you use a different turntable? A lot of people claim otherwise but I just don't...

I just returned home after picking up my Garrard SL 72b from the repair shop. I immediately hooked it up and noticed a clinking sound when the platter is spinning which is throwing the speed off. This is the first suspended turntable that I have owned. The Garrard is new to me so I am not...

alrighty guys, Im slowly getting back into my R2R world and have questions: I lost my capstan sleeve (i only have the chunkier one), and need another for recording/playing 7.5 IPS tapes. As far as the rubber pinch wheel/combination goes, I've always been able to use either no capstan sleeve...
