Here is the HK Festival monaural tube tuner from early 1950s. My memory of its built in equalization curves was faulty; the photos show "Eur", "RIAA", and "LP", not Columbia or Decca. I wonder what were the differences between Eur or LP vs RIAA.
A phono preamp with equalization selector
Hi all,
what do you think about the record equalization selector? I have several Deutsche Grammophon records from the '70. A friend noticed me they should be played with Teldec equalization plus inverted polarity, features that my phono preamp doesn't have. I know this is typical issue if you have old records (60-70s and before). What do you think? Do you agree? If so, which machine may you suggest me?
Thanks!

@elliottbnewcombjr Nice piece! Take another look at that front panel. The EQ curves were very much standard by then. 'NAB' is a tape equalization. RIAA and the 'RCA Orthophonic' curves were pretty much the same thing; RIAA being for stereo. AES and LP were two alternate mono-only curves and the '78' curve was an approximation of the most common 78 curves of which there were quite a few. |
atmasphere"RIAA being for stereo. AES and LP were two alternate mono-only curves and the ’78’ curve was an approximation of the most common 78 curves of which there were quite a few." That President II was 1958, the year Stereo LP’s came out. MONO EQ.: all my 40’s and most of the 50’s Mono Jazz LP’s are playing thru my MM RIAA EQ. Close enough to AES and/or LP EQ? 78's. Using a Modern TT with 78 rpm, correct stylus, they would also go thru RIAA. |
