Re: [ARSCLIST] Exactly how many labels did RCA press records for in the 50s/60s ?

[Roger and Allison Kulp <thorenstd124@xxxxxxxxx>]

I think I had once read something to that effect.I do,have a couple of questions :

I believe all of the Decca pressed RCAs of the period used Dynagroove stampers imported from the USA,did they not ?

What of the RCA Red Seal reel tapes of the period ? How are they different,or similar to Dynagroove Lps ?

----- one of the ideas of Dynagroove was the alleviate tracing distortion due 
to spherical stylii. Elliptical or bi-radial tips like we know them were very 
rare. So, the groove was pre-distorted in a way that only a spherical stylus 
could un-distort. Using modern elliptical stylii is breaking the systems 
approach.

----- I suspect that Dynaflex was just a gloss on saving vinyl due to the oil 
crisis (1973?), and that was scandalous whoever did it. 

Kind regards,
