How are you playing your precious MONO Vinyl?

dwette

you are correct, about the AI error I posted: many true mono cartridges have 4 pins (both of mine do), and RIAA being used (for some, not all) earlier, from 1954

"From Wikipedia, the free encyclopedia

RIAA equalization is a specification for the recording and playback of phonograph records, established by the Recording Industry Association of America (RIAA). The purposes of the equalization are to permit greater recording times (by decreasing the mean width of each groove), to improve sound quality, and to reduce the groove damage that would otherwise arise during playback.

The RIAA equalization curve was intended to operate as a de facto global industry standard for records since 1954, but when the change actually took place is difficult to determine.^[1]

Before then, especially from 1940, each record company applied its own equalization; over 100 combinations of turnover and rolloff frequencies were in use, the main ones being Columbia-78, Decca-U.S., European (various), Victor-78 (various), Associated, BBC, NAB, Orthacoustic, World, Columbia LP, FFRR-78 and microgroove, and AES. The obvious consequence was that different reproduction results were obtained if the recording and playback filtering were not matched."

My speakers are new enclosures with drivers from 1958, I pulled from the Fisher President II Console I inherited from my Uncle Johnny, here’s it’s Control Panel’s choices for LP and Tape

Fisher President II, 1958

 Most unique is ’Stereo Radio’ which was a brief period of Live Binaural Stereo Broadcasts.

 Excerpt from

https://www.radioworld.com/columns-and-views/roots-of-radio/how-fm-stereo-came-to-life

 “A sort of marketplace “AM-FM stereo” system standard for binaural broadcasting appeared, with one channel on the AM (left) and the other on the FM (right). These were the days before NRSC audio frequency reduction, so the audio response on AM was notably better. Vendors offered better receivers to the connoisseur; and the reception environment was far friendlier than today, with less electrification, less band noise and fewer stations. AMs could sound pretty good; all FM signals were hi-fi mono.”

 Tune the FM Mono Tuner to CBS and Tune the AM Mono Tuner to CBS. Select ‘Stereo Radio’ on the Control Panel

I’ve re-coned the 15" woofer a few times over the years, the horns are original ’impregnated linen’, seemingly indestructible although I did burn out a coil once blasting my reel to reel copy of Iron Butterfly

here’s the back off showing the innards, 3 wheels for alternate toe-in/placements, front block to tilt them back to aim the tweeters at seated ear height.

A pair of L Pads (not shown) are mounted in the back panel to adjust both horn’s volumes in the space, using Test Tones and an SPL Meter on a tripod at seated ear height.

Notice, no internal bracing, yet nothing vibrates off the slanted tops

OP, I’m excited for you, I had a Thorens TD124, single arm, I can imagine the Garrard’s are a similar degree of AWESOME. Best Bass I ever heard, here or anywhere since. I’m happy with what I am getting, but you never forget the difference once you have had it.

It’s funny to see them on spikes, maybe in a concrete bunker, I need a final layer of rubber even with my current JVC Victor TT81 player (since wrapped in black tape)

 

the TD124 was very sensitive to vertical vibrations from my springy wood floors, and I need/prefer a dust cover.

These are a combo spike/soft, and adjustable, has anyone tried them______?

Everyone, 

the Aurorasound EQ-100 is uniquely different, from the manual:

"When a stereo cartridge is used, any vertical signal on a record is cancelled by an internal circuit of EQ-100. Only the R+L horizontal signal are detected to assure a superior sound stage with less noise."

Cancelling any vertical input seems to me FAR better than producing the noise and then summing the noise in both channels, that is my biggest objection and what I referred to as MUD on top of the Mono Content (Dual Mud?).

It may be the best way to use a single arm, single stereo cartridge to play a Mono LP. Thus my objection that it does not have provision for proper Stereo, ... and

it always ends up Line Level Out (after doing what? complicated for infrequent use, the switches were left in what position?)

 

 

@elliottbnewcombjr Thanks for your posts, I always find them informative.

lewm,

"For the umpteenth time, using a mono switch when playing a mono LP with a stereo cartridge is not per se going to increase noise because of "sum"-ing. Phase cancellation takes care of that, and reduction, not summing, of common mode noise is the principle benefit of using the mono switch."

I keep forgetting this, because not always but MOST OFTEN, using my True Mono cartridge sounds FAR better, MUCH LESS NOISE than using my Mono Switch.

My copy of this

https://www.ebay.com/itm/224036490489

is UNLISTENABLE with a Stereo Cartridge, a history lesson at best, (where’s Louis?). When played with my Grado ME+ Mono, $185. elliptical, it is both enjoyable (there’s Louis) and is the easiest demo I can play for others.

A muddy mess with terrific sounding AT33PTG/II Stereo’s advanced stylus via mx110z’s Mono Switch. Play with the Grado Mono Cartridge: Individual instruments and voices become distinct (not imaging, but distinction) to the extent you can imagine the individual players. Definitely DOES NOT OCCUR using the Mono Switch.

Where is phase cancellation mentioned?

 

If Phase Cancellation is ASSUMED to occur, it doesn’t occur perfectly, not in my experience.

You do not need to spend a lot of money for True Mono Cartridge, $185. is the current price of the Grado ME+, elliptical stylus, if you want to go beyond that, ok, but not needed to simply enjoy your current or future Mono LP's,

especially if you listen to Jazz, so many greats made their reputation before Stereo. If it's in good shape and mono, you will have no hesitation, recording techniques were already very good, buy, plan on it sounding INVOLVING..
