I'm looking into buying a record player. The one I'm looking at has 33 1/3 and 45 RPM.
It doesn't have 78 RPM, would this be needed?
I have looked at my vinyl and most say 33 1/3 or 45, however some don't mention their RPM.

Thanks.

a 33 1/3 rpm record on a turn table uniformly reaches its operating speed in 2.45 sec once the record player is turned on.

A)what is the angular distance traveled during this time

B)what is the corresponding arc length in ft. in the circumference of a 12-inch diameter record?

i need to know how to do this for a test tomorrow, would appreciate ur help very ,much so i don't fail

Bobby socks, black suede penny loafers or Ivy League black & white oxfords? Sock hops, duck tail haircuts or ponytails, starched collars worn up to look cool, tiny little plastic colored clothespin worn on the collars? And Rock & roll music on a 45 RPM record played on a small record player? (sigh, the good times todays teens missed out on.) What memory stands out in your mind?
Ivy League oxford had the buckle on the back of the heel. If you wore the buckle open it meant you weren't going steady with anyone.

thanks just making sure.
its a crosley
it says i have an option of 33, 45, and 78 rpm.
will the big records still play and fit on my player? will i just have to put it on 45rpm and it will work?

i got this great 3-speed record player it can play 33-45-78 rpm and i was wondering where some one could find cheap records

when the author was a teenager, the rate of rotation for popular music records on a record player was 45 RPM

a) express the rotational velocity in rev/s
b) through how many revolutions doesw the record turn in a time of 5s?

please explain in an easily understandable way

big hub hole for 45-RPM discs (even though small-shaft players can be adapted for those)?

Will you come back and see my responses to yours, please?

Thanks,
Mike Christensen
Whow, thanks, Kim! That's quite an article! It seems odd and shallow and selfishly lame that a company would change the hole size just to lock consumers in, but that article sounds like it's speaking the truth. That speed optimization info. sounds pretty interesting.

But then other manufacturers defeated that lock-in effect by making hole-size adapters. Hmm, imagine that!

Thanks!
Mike

in the 1940`s record players were made to spin at 78 revolution per minute (rpm). a more modern record player spins a record at a rate of 45 rpm.if both turn table spin for 9 minutes find the difference in the number if turns they make.ORGANZIE YOUR INFORMATION AND EXPLAIN HOW STEP BY STEP

Hi. I recently was given a second hand record player by a friend. I am ashamed to say that although i have listened to loads of vinyl records when i was a kid (my dad lost all his records and player during a move) i do not know anything about actually playing a record! i am 19 now. I have always loved the sound compared to cds and now i want to build up a vinyl collection from scratch. I still have one 7 inch record and another 12 inch one.My player Semi-automated turntable and has two speed knobes - 33and 45.and as far as i can see there is no needle on the edge of that handle thingy. its just a square like thing. Can someone explain what all this means very simply. I have spent hours online trying to read up on this but i have gotten even more confused with all the terms. what is EP and LP? what is 78 rpm, 45 rpm, 33⅓ rpm? what records should i buy? what player plays what kind of record? i can't ask my parents cause they are not around.Please please help me out. sorry if i sound stupid but this is a part of my childhood that i want back. thanks alot
My player is a semi-automated turntable Sherwood PD-701B

as for my budget..i don't really have one yet. as in I have to save to get what i want so preferably something reasonable and mid-priced.i cant tell you an exat price because i have no idea how much these things cause.as for music - I absolutely love the beatles, bob dylan and aerosmith.and some motown stuff- like smokey robinson. thanks alot for the help.

This is a bit embarrassing, please bear with me because I know nothing about this stuff. I want to buy an old vintage record player and a bunch of records, but I'm looking on ebay and it states whether the records are 33 or 45 or 78 RPM. I have no idea what this means, and how do I know which are compatible with a record player? Are they all compatible? Is one of the RPM better than another? Please help me out, thanks!!

I just purchased a vintage Crosley record player that is built into a cabinet and has a radio next to it. I am guessing it is from the 40's or so, it only plays glass records.
I am wondering 2 things:
1. Where can I get information on this record player
2. I can't play any of my vinyl records without it sounding like the chipmunks. The record player has only one speed but I have a few RPM adjusters that are circular shaped... but have NO idea how these work... anything will help!

Ok - the last time I used a turn table was about 23 yrs ago so I can't remember the name of the little circlar "disk" that went fit inside the record hole to make it fit the turn table. There was also one that fit onto the turn table (as opposed to the actual record).

I need the names of these do I can search for one on Ebay....I have some old records I want to play for my kids (9 & 3 - never seen a record!!) but they're 45's & don't fit the turn table.
Just searched Ebay - is this it?

I do a small business of musical antiques. dealing gramophones, gramophone records, valve[tube] radios.
vinyle records of 33 & 45 rpm. and 78 rpm wax records.
servicing record players, gramophones and tube radios are my speciality. wish to open a web site for assisting service of gramophone mechine to public. the diagrams and manuals are underway. is there any other simular site ?

not looking to get much for whole collection - all used - no original packaging - also have a Sears Silverton portable 78 rpm crank-up record player. this is portable (suitcase style) not in the wood box with the horn. works great!!!!!

im really into old records and my grandmother has soo many 45 records and she sold her record player 5 years ago...so i am looking for a 45 rpm record player. do you know where i can find one?

After my father, who was a former square dance/round dance caller, passed away my mother asked me to find out what his old phonograph/speaker system and collection of 45 RPM square dance/round dance records were worth and how to go about selling them. Many of the records have the dance cues as well. I don't know whether they would be classified as collectibles or not.

Thanks for any suggestions.

I'm having trouble choosing a good record player make; here's the stuff that I want:

1) able to play 33 1/3, 45, and 78 rpm speeds
2) semi-automatic arm (so that lowering it onto my vinyl won't feel like a delicate surgical process...)
3) USB, USB, USB!! It's utterly important that I can transfer my old vinyls onto my computer.
4) Decent sound quality... I'm counting on the converted mp3 files to sound great on my speakers anyway, so I don't really need audiophile quality direct from the turntable. Still, I want "decent" sound.

Any ideas?

If you play a 33rpm record in a 78 rpm record player what will happen? Will it play it too slowly/quickly? will it play at all?

I have a record player that is a big black box thing, but it doesn't work very well. I also know that bad quality record players can destroy records. So I'm looking for a good quality record player without an entire stereo system. The records I have are mostly 33 rpm's.
Thanks.

A phonograph turntable reaches its rated speed of 33 rpm after making 1.1 revolutions. What was its angular acceleration in radians/second^2?
m=mass x velocity x radius

I know that,

Angular Acceleration = Change in angular velocity / Elapsed Time

Having trouble plugging it all together

Thanks guys!

I want to make a wooden 45 RPM record adapter. I am speeking of a basic short spindle model. Please list your type of measuring tool.... ruler, micrometer ect. I dont have a record player or a 45 to measure as this project is a favor for a friend. Thanks.

For Christmas in 1966 I got this record player & a whole bunch of record & film strip sets. It played the film strip as it played the record. I can't remember the name of it. I had the story of Persephone & the Pomegranite, A spanish one with the months of the year, Peer Gynt & many more.
Thank-you. I found it. It turns out it was 33 1/3 RPM's. http://search.ebay.com/show-n-tell_W0QQfnuZ1QQfsooZ1QQfsopZ3QQsatitleZshowQ20Q27nQ20tellQQxpufuZx

I have a Columbia 360 record player from the 1950's and it plays records a bit too slowly. The 33 rpm speed needs to be adjusted a bit. Is there an internal adjustment dial or screw that will do this on old record players?

A phonograph turntable reaches its speed of 33 rpm after making 1.7 revolutions. What was its angular acceleration?

I know how to do this problem when a time is given, but not when they provide how many revolutions it took to reach the 33 rpm.
