The lines are not so clear cut, however, as there exist such things as 12 inch singles, which instead of holding a whole album seek to play an extended mix of a single or simply hold a longer form song without sacrificing any of the sound quality.įor this reason, a 12 inch single record spins at 45 rpm usually, particularly popular among various styles of dance music, where the audio quality over massive speakers is integral to the sanctity of the vibes.
In fact, the term single comes from these days, when a single set of songs would be held on these 7 inch discs and played at 45 rpm for the sake of higher audio quality. Where 12 inch vinyl records are traditionally used to hold longer form releases like albums or EPs, the 7-inch has come to hold shorter releases, like shorter EPs and singles. The 7 inch record comes with the task of holding sound from quite a different angle. This tradition continues to this day, where the dichotomy of 33 vs 45 vinyl comes to symbolize the parallel dichotomy between 12-inch records and 7-inch records. This harkens back to the early days of vinyl technology when Columbia Records began selling these larger discs under the pretext that they could hold significantly more music than any other existing disc at the time, including a whole range of vinyl record types. A record played at 33 rpm will tend to be around 12 inches, in fact. Generally, a record played at 33 rpm will be larger than a record intended to be played at 45 rpm. Last edited by vitanola on Jan 3:27 am, edited 1 time in total.One of the central differences between 33 vs 45 vinyl rpm is the respective sizes of these kinds of vinyl record speeds. Industry wide sales of phonograph records in 1932 amounted to only about six million units, as apposed to the hundred-fifty million unit sales of 1928. In that year it was assumed that the industry was duing, and would take only a couple of years to wind up. I suspect that the decision by RCA Victor to dispose of a considerable quantity of their induction disc motors at cut prices in the spring of 1932 may have a grreat deal to do with the appearance of these motors in Philco combinations in the succeeding years.ġ400 unit sales was prety good for a phonograph in 1932. It appears that early 1932 combinations continued to use the green flyer motors. The 211 combination used the Victor pickup on a Capehart drop changer. The 1931 vintage models 270 and 290 used Victor pickups on the "inertia" tone arm, and were fitted with General Industries "Green Flyer" motors. Most examples of the Concert Grand used a Victor pickup and a Samgomo motor, although some examples are known with the General Electric Induction Disc motor. Paul Philco used RCA (actually Victor) pickups and arms in all pf their combinations until at least 1934. The depression and the relatively high price of the set basically forestalled any chances of it ever realizing a meaningful sales volume only ~1400 units were sold. Certainly similarities in the tonearm and player are evident. I understand that its phono mechanism was obtained from arch-rival RCA. Philco also manufactured at least one 33rpm radio-phono in 1932, their 23X:. The Depression is over" Herbert Hoover, June 6, 1930 "Gentlemen, you have come sixty days too late. Philco built the 33 1/3 adaptor turntable shown in the eBay listing under contract to the Columbia company. The Western Electric vertical cut transcriptions of the 1930's and 1940's also were recorded at this speed, and they were really quite astounding, particularly as to high frequency response and dynamic range.
The Vitaphone discs were all recorded at 33 1/3, and they can have remarkable fidelity. Issues in this format were few, and were discontinued entirely in 1941.ģ3 1/3 was also used for high fidelity purposes. The lesser machines in the 1934 product line were again offered as 78 only. Most of the 1932 line of Duo instruments were fitted with the 2 speed turntables. The Victor Program Transcriptions were introduced in 1931.Īn inexpesive adaptor (a new turntable with a planetary reduction gear) was made to allow these new records to be played on older Electrolas. I have a Newcomb 2 spd transcription player dating to 1947.īy the way, Nice photo of the record player I'm finnishing for you.
#33 rpm record tv
I used to have a very rare Capehart radio, tv phono that played 33's, and, that was 1947. RCA was making 33 rpm records with the 78 grooves as early as 1938, and, several makers made the machines to play them.
