What is a mildly cheap turntable?

I recently scored a great deal on a full stereo set, it included a 5 cd changed, a dual cassette player (with high speed dubbing), AM/FM tuner, the amplified for it all, and of course, to put the cherry on the top; a very nice Sony Turn table with 2 speeds; the common 33 1/3 and then the other common, 45. Sadly, I ran a test (after noticing bad sound quality) on it and realized it spun at approximately 29 /12 RPM, causing bad distortion in the record. I checked the motor and belt and neither of them looked damage – not that I know for sure since I am not completely familiar with Record Players.
I just assumed the Motor was not functioning right, and I was told getting my turn table fixed would cost as much as buying a new one, so, I have been on the search for a somewhat cheap turntable.
It needs to have RCA cables to connect into my amplifier, and needs to be thin to be able to fit in stereo case that all the equipment came in. (not like laptop-thin, but you know, nothing humongous). Aside from that, I only use 12″ vinyls, and don’t plan on owning and 45s, so so long as it can play 12″ vinyls – at the correct speed – I am fine with that.

I need a USB turntable.?

Hey,
I know there are a lot of questions already about USB turntables, but my question is pretty specific.

Okay…so here’s the deal. I’ve got a stack of records, old and new, as well as access to my dad’s collection of several thousand (I’m not exaggerating). Currently I have a very high quality turntable to suit my audiophilia, but I have big issues with it because, instead of selecting the speed with a switch (as you do on most modern turntables), you must turn a dial that affects the speed of the record. And I have to reset the speed every few weeks with normal use, as well as every time I switch between 45 and 33 1/3 RPM. And this is a pain in the ass that I’d rather not deal with.

I also have several records that you either can’t get or I just don’t have digitally, so I’d like to get one ‘o them fancy USB turntables, so I can appreciate my vinyl collection on my iPod.

Oh, and I have a speaker system in my room.

So I need a turntable that’ll accomodate all that. Yeah.
So here’s a more specific, to-the-point list of what I need in a turntable…

1. Good quality sound (I can deal with not perfect sound quality, but I want good sound).

2. Ability to switch RPM speeds by switch (this is a feature on nearly every modern turntable).

3. Ability to transfer my music from vinyl to digital, so a USB turntable.

4. Audio outputs, so I can hook the turntable up to my sound system.

So far I like (and have heard good things about) Crosley turntables, but I don’t think they have audio outputs, which is a fairly big turnoff for me.

So…any suggestions?

How many grooves are in your standard 33 1/3 LP? Hint: it’s the exact same for all of them.?

Now for those of you who don’t know, way before CD’s and cassettes, there were these things called “records” and they were made out of vinyl and the “record albums” were played on a Turntable and there were two speeds to play them at 45 RPM and 33 1/3 RPM, the albums were called LP’s which stands for “Long Playing”. Anyway, when the needle came down onto the record it played the music. So, boys and girls, how many grooves are in your standard “record album”?
It’s OK to ask your parents as long as they are over 50!!! LOLOLO

Coefficient of Static Friction question?

A beetle standing on the edge of a 12 in. (~0.30m) diameter vinyl recording of “Sgt. Pepper’s Lonely Hearts Club Band” is whirling around at 33 1/3 rpm. What is the poor things coefficient of static friction?

I converted 33 1/3 rpm to .524 m/s… I think that it correct. And using that and V= (Ms x g X r)^1/2 I found Ms=.187.

Can anyone confirm this or show me where I went wrong? Thank you!

Physics help!!!! What equations would you use?

In the “old days”, long before CD’s and MP3’s, people listened to music using vinyl records. Long-playing vinyl records spin at a constant rate of 33-and-one-third rpm (revolutions per minute). The music is encoded onto a continuous spiral track on the record that starts at a radius of 30 cm from the center and ends at a radius of 10 cm from the center. If a record plays for 24 minutes, how far apart are the grooves in the track on the record?
That didn’t work!

The answer was wrong. :(

Easy physics, need help?

An old-fashioned single-play vinyl record rotates on a turntable at 54.0 rpm. What are (a) the angular velocity in rad/s and (b) the period of the motion?

Dumbest computer tech question you got from a relative?

I think my favorite was asking of they could slip their old 45 RPM vinyl records in the DVD player to listen to them.

angular speed and time period help please?

An old vinyl record rotates at 45 rpm. What is it’s angular speed in radians per second?

With reference to questions 1, what is the time period of the 45 rpm record? Please give answer in seconds?

Any help with this question is appreciated.
