I know about R.I.A.A. But I wonder if '50's - early '60's turntables (record players) that had 33 and 1/3, 45 and 78 r.p.m. had necesarly R.I.A.A.?
The stylus most no be for microgrooves or what do you mean? |

A standard stylus for microgroove records (LPs) will sit in the bottom of the larger 78 groove. The results are horrible. Purists will have a range of styli for 78s, choosing the one that works best with a given disc. I use a Shure N75-6 stylus (in a Shure M75 cartridge) which is a good compromise for most 78s. Not sure of its exact size.
RIAA equalisation will make most 78s sound bass heavy. You can do an approximate correction with tone controls or build a pre-amp with switchable EQ. A few pre-amps such as the Quad 22 had switchable EQ as standard. Ordinary record players that could play boht LPs and 78s didn't have such switching. You just used the tone controls to get the sound you preferred. |

Once LPs had settled on RIAA that was usually the only equalization circuit in the system, but there were some exceptions.
I have a Fisher (IIRC model 50C) that is a mono tuner/phono preamp and it had a few switchable equilization options I think they were RIAA, EUR, 78, and possibly something else...I don't do a lot of mono listening so that Fisher has been in the closet for a good 5-10 years now.

So it isn't the original sound from the record...

I'd advise against taking seriously any comments written by dude111. I've read them for the past 10 years, more for amusement than anything. Some of the crazy stuff he believes is hilarious...for example the dude won't update to anything newer than windows 98 (or was it XP?) Because he read some cock and bull tall tale that there's some kinda mind control digital noise baked into the newer opperating systems. He believes all digital audio and video is terrible. And if you read his replies to threads he started to ask how things work it becomes evident he has close to no technical knowledge, and even less aptitude.
He's good for cheerleading, necro-posting to 10+ year dead threads (if you can even call that a good thing) and seat warming his account here. I kinda think of him as the only bot that hasn't been kicked off VK for being a bot.

Ah Dude111 is alright, he annoys audiophools and know-it-all types on other forums I haunt. I’d buy him a beer or..erm maybe a chocolate milk or instant ice tea
Anyways here’s what I play 78s with. A GE VRII with a turn around rather than turn over stylus. Push down to flip between LP and 78. It has no vertical compliance so NO playing stereo records with this one |

A blanket statement that you aren't hearing the original quality just because the YouTube posting is digital is wrong. It depends on what was done to make the video.
If the sound for the youtube video is being picked up by a microphone in front of the loudspeaker, then the mic arrangement and room acoustics can affect the result much, much more than digitizing the signal ever could. However, the audio may have been processed to reduce noise, which would make a big difference as well. So, are you interested in the overall result using the vintage phonograph? That may be what you have here. If you want to know the quality of the record and cartridge output, then you need a recording of the equalized signal. Again, straight digitizing without additional processing will not contribute any audible effects. Disclaimer: using too low a bit rate for the audio could produce audible effects. In this video you can definitely hear the level of distortion typical of recorded music of that time, which the digital processing does not contribute to in any audible way as far as I can tell. |

I got this replacement for a Cobramatic in a 1956 Zenith "Rhapsody" https://www.thevoiceofmusic.com/cata...th&Categories=
I Then advised the new owner of this equipment that he cannot play stereo records. It would not be hard to swap in a stereo cart but why do this for a pre-stereo unit? GE carts seem to be a favorite though I have never seen one in the wild.

Some of the 4 speed changers did have a funky "compromise" stylus that was in-between the standard 78 and 33 tip sizes.

I have one of these, a 10" 78 RPM record made in late 1970 that was part of a promo package given out to radio stations promoting the new at the time Uncle Charlie And His Dog Teddy album. I have nothing to play it on after I sold my Dual 1219 years ago. When I DID have a turntable capable of 78 it sounded great, high dynamic range for sure.

It's microgrooved or haves big grooves?

Ha! Yeah, next time I'm talking to the mastering engineer I'll ask ...☺
Pretty sure it was cut to "78" standards. It takes up the whole side for a 3 1/2 minute tune. |
