Some felt that the sound quality actually improved, due to the purer vinyl used, and better processes for removing impurities in the vinyl compounds others felt that Dynaflex pressings were noisier and lacked bass frequencies compared to conventional records, and also had more "rumble" (low frequency noise) than conventional thick pressings. Opinions from record collectors and audiophiles are divided as to Dynaflex's sound quality.
This flexibility also gave them theoretically more resiliency in shipping, resulting in fewer returns from retailers due to breakage and cracks. Some were so thin and flexible they could actually be bent nearly in half. RCA's Dynaflex records varied somewhat in thickness, but most literally "flopped" back and forth when held between the hands. Such "reground" vinyl records typically sounded much noisier and scratchier when played than a record made from new or "virgin" vinyl collectors noted that records pressed from "reground" vinyl sometimes had small remnants of paper labels or other materials embedded in them. At the time, as a cost-cutting measure, most industry record pressing plants were using recycled or "reground" vinyl, taking old and unsold records, cutting out the center with the paper labels, then melting the restĭown and reusing the material to make new records. Rather than using the stiff plastic material used by conventional vinyl pressings, Dynaflex records used a softer, pliable formulation that allowed RCA to use less material, saving money and also making the record appear to lie flatter on turntables.

You'll find this dating system used on some 45 rpm re-releases of RCA material originally issued earlier in the century on 78 rpm recordings. This dating system actually starts earlier in the century, as follows: Examples of RCA Victor regular releases and custom pressings are: A typical RCA matrix number contains eight digits of letters and numbers. In the list above, the letters: I, O, Q, V and Y are skipped. Notice that the system skips any letter that could be easily confused with a number. The following chart shows the dating information from 1950 to 1975: In 1955, RCA changed it's system slightly so that the first letter alone represented the year.

The code is located in the first letter and number of the eight digit matrix number up to 1954. There is a code in the RCA matrix numbers that identifies when the record was mastered (it was usually pressed and released immediately thereafter). Their pressing plant in Indianapolis, Indiana pressed 1000's of local label releases in the area throughout the 1950's, 60's and 70's. RCA custom pressed a large number of local label records across the United States from the early 1950's on. Go To Discography of all RCA Pressings in our Database
