!970s British RCA Red Seal.Dynagroove.

Post by goatbreath » 02 Jul 2019 20:30

I am reading that RCA Dynagroove with it's predistortion was used into the 1970s..
Does this include the British Plain Label RCA Red Seal records if it doesn't have Dynagroove in big writing on the cover.?.Also the later Gold Seal Reissues of the original Red Seal LP's or were new Master Stampers made.?..Are these Dynagroove too..?
I thought RCA only used this technique in the early 60s,but it seems they used it into the 70s..

RCA made a big marketing deal out of Dynagroove when introduced. The reception was a mixed to say the least. They certainly did not make a hoopla about dropping Dynagroove in the '70s.

The dynamic compression and pre-distortion that was the Dynagoove process had to be applied to the tape before cutting. If the "Dynagoorve-ed" gereration tape was used for disc mastering when the Gold label or other reissue was cut then that would have all the dubious glories of the process.

Frankly I have some Dynagooves that sound "okay" but RCA never got back to the wonderful sound they got in the late 1950s with legendary Shaded Dog and Black Dog labels of early stereo.

Thanks,,Good to know that... :D
I have a small handful of US Pressed Nipper Dogs,not sure which ones are shaded and they sound very alive sounding..I have a fair old classical collection,but most are represses or Later recordings..
.
My RCA's are mostly on this Label..The Red ink seems to vary a little..

from what research I have done its not clear if all dynagroove records were actually 'processed' with the predistortion. Easiest way to tell is to see if they sound better played with a conical stylus.

I was pretty much thinking about using a conical as a default for RCA Red Seal classicals..I am now wondering if Bowie Ziggy and Lou Reed Transformer etc may be better with conicals too..

Just for clarification: No British RCAs are going to have Nipper the dog on the label, with or without shade, of any vintage. EMI holds the copyright on Nipper in the UK. Any doggies on the label of an RCA suggests USA source.

The British RCA pressings were generally better in the 1970's than the USA ones until around 1976-1977 when things began improving. Dynagroove was introduced in 1963, after the furor by audiophiles, and music lovers, the process was quietly phased out, though the name stayed around. Dynaflex's introduction was another RCA epic fail.
