23 3/4 x 14 1/4 x 11 3/4 inches

The Tweeter suffered a bit in the L100 and was improved in 
some of the latter iterations (like L 166). One of the best

As usual, Bob shows up with information only an extraterrestrial should know!
Your archives must be a literal museum there Bob, as over the years you have
contributed information that almost nobody else seems to know, remember or have.
Great stuff and even better work! Thanks Bob.

Thank you Bruce. Interesting on the dimensions for the depth, as mine are 11 1/4
deep. Being as this model was produced for four more years, perhaps it changed?
I purchased them in 1974 for $300 each.	
	
I noticed no weight was given. I wonder why?

I was noticing that all of the speaker systems I have from 1995 to 2003,
crossover at 400-450 Hz and 2000-3000 Hz. All are three-way systems; B&W 630,
Paradigm 9S and Paradigm Monitor 9S.	
	
Whereas the midrange and the woofer used to share the low mids and the midrange
and the tweeter used to share the high mids, not so any longer.	
	
The woofer and the midrange appear to do less and the tweeter more. Why is this?
I do not personally consider "highs" to start at 2KHZ or 3KHZ, more like 4.5 - 6
KHZ. Depending how you look at the math, allowing for variances among
manufacturers, the older systems used the woofer about 3.5 times more than today
and the midrange 5.8 times more than the present. Why is so much of today's
audio being fed into tweeters at frequencies four times below where they should
be coming into action at?	
	
Now when my fourteen year old grandson can tell Grandpa what speaker system is
being employed from the opposite end of my home, I need to turn it down! (LOL!)
Just kidding, as I do not like to experience the room shake effect while
listening to music. The music that I feel is due to emotion, not vibration. He
can tell if I have the James B. Lansing Century L-100 in use or the B&W 630
bi-wired. So it is not just a nostalgia issue here guys! If a teenager can tell
without looking, there is something happening!

In my opinion...(what do I know...and I cant hear anymore 
over 9KHz):

I think the problems started with stereo. There was a need 
for the phase of the mid and highs to have some consistant 
relationships and with the woofer and it's depth in the face 
plate, this was not too possible due to all of the resulting 
reflections from the cone and mounting. The mids emminate 
from the center of the cone and a number of manufactureers 
made little balls and junk to try to get the mids out a bit 
nearer the front, but these "fixes" were not too good. So 
they took more of the mids away from the woofer and gave it 
to a more planar mid range speaker. Now the highs had an 
even more difficult issue with dispersion or the angle 
coverage. Before stereo, the issue was not too bad as the 
highs bounce around a lot anyway, but with the "need" for 
stereo spacial imaging, you need a direct path and so the 
tweeters got more of the attention and really set the stage 
(so to speak).
Some of the finest speakers were the big horns, but they too 
suffer from spacial phase issues that screw up the stereo 
imaging. For real sound, we should go back to mono. (now 
that is from a guy with 8 speakers in my office running 7.1 
SACD)

HI DUANE, GLAD TO SEE THAT YOU ARE STILL IN THE HUNT. I STILL READ MOST
OF YOUR MAIL ABOUT THE OLDIES BUT GOODIES. HAVEN'T BEEN ON HF IN A FEW
YEARS, LEARNING TO LIVE WITH AND ACCEPT MY PROBLEMS. HOPE ALL IS WELL
WITH YOU AND YOURS. 
YOUR DISCUSSION ABOUT THE JBL SPEAKERS WAS VERY INTERESTING. AS YOU KNOW
I LOVE MY TWO SETS OF L-100'S. THEY REALLY SOUND GREAT. I ALSO HAVE A
SET OF L-166 SPEAKERS THAT ALSO SOUND REAL GOOD. I DIDN'T REALIZE THAT
THEY WERE SUCH A GREAT SPEAKER. I ALSO HAVE A PAIR OF JBL 4310 CONTROL
MONITORS. I DON'T HAVE THE EAR THAT YOU AND SOME OF YOUR FRIENDS HAVE
BUT THEY SEEM TO SOUND GREAT AND CAN TAKE EVERYTHING THAT I CAN GIVE
THEM. WHERE DO THEY STAND ON THE LIST COMPARED TO THE OTHERS??? PLEASE
ADVISE, DON WC2E

Subject: [Vintage-Audio] Re Stylus For Sony 5520 Turntable
Message-ID: <200508260519.j7Q5JAd8028626@smtp.usol.com>


	
Hello All, 	
	
I have a Sony (Marantz?) model 5520 two speed turntable from 1974. The model
number has "MD 88858" following it. I am not sure what this means. Anyone? 	
	
I have a dilemma. The Shure M91ED cartridge is no longer available, but the
Stylus N91ED is. Now thinking ahead, I purchased a new Stylus some years back. I
had the entire unit checked two years ago, and the drive belt replaced. This is
the first new belt she has ever needed in thirty-one years of service! Actually
twenty-nine years at the time the new belt was installed. I also got a
replacement belt and sealed it up, just in case.	
	
I changed the Stylus last year. It has played just fine ever since. But today
when I was playing some vinyl I noticed what I thought was more needle tracking
noise than was normal.	
	
Now I was kneeling at the time and was only three feet from one of the floor
located speaker cabinets, B&W 630's. Taking this into consideration, I still
believe the noise was more than it has been previously.	
	
I tried several other vinyl albums, two of which I purchased still sealed and I
knew had as little wear as one could hope for. The needle noise was less, but I
still think more than is normal.	
	
Assuming I am as sane as I have ever been, (No comments from Donald or David!),
what might cause this?	
	
Is it possible that I have a tiny dust ball far enough up the stylus needle that
I am unable to remove it without a sighted person using a fine Camel hair brush
to dislodge it? Would such an obstruction to stylus motion cause this to begin
with?    	
	
Further assuming, (Donald D. in NY put a cork in both ends! Dave P. in TX, just
stuff a golf ball size scoup of peanut butter in your mouth, we will leave the
other end uninhibited to prevent an explosion!), if I must replace the
cartridge, who still makes what to fit into the tone arm of the Sony/Marantz
5520?

Duane,

there may also be some shelf life limits on Shure stylus units.

The rubber inserts that make up the pivot point for
the stylus assembly in the holder will go bad over time
and cause problems.

I had a Shure V15 Type 3 that failed like that, and they
have (had) some trade-in program for stylus units.
The type 3 is no longer produced either, and they suggested
another unit, which they supplied, at a reasonable cost.
This was about two years ago, and I do not know anything
about the current status with Shure products.

Hello All, 	
	
Thanks to a good friend who took pity on me, I have made arrangements to get a
NOS Shure M91ED cartridge and N91ED stylus.	
	
Monday evening I removed the one year old N91ED stylus I had purchased new five
years before and saved until needed. I installed it in July of 2004.	
	
Now I thought it very odd that it failed in one year, when the previous one had
been working for twelve years! No, I am not too cheap to buy a new stylus, it
simply did not need one! Truthfully, since I bought the Sony 5520 turntable in
August 1974 I have only had to change the stylus once. 	
	
I can still play the original vinyl that I purchased new for $3.49 in the
sixties.	
	
here is what I need to know:	
	
What is the recommended tracking weight for the Shure N91ED stylus? 	
	
Has there been any manufacturing changes made during the past ten to fifteen
years that would shortn an ED stylus life?			
	
How common, or likely, is it for a tone arm to move slightly, just enough to
change the tracking angle on the stylus to produce either distortion or a pop on
some bass notes? Keeping in mind, that the turntable is totally covered in its
protective heavy plastic enclosure, is never moved from its location inside the
stereo console. Only the plastic cover is opened to play a record. There is no
way anything can strike the tonearm.	
	
I am asking because it was suggested to me that that was the problem and not a
damaged or defective stylus.	
	
Does anyone know of a satisfactory replacement cartridge and stylus combination
for the Shure M91ED and N91ED?	
	
FYI: I almost never let the turntable cue a record. I do it manually. 	
	
Confession: I just remembered that about two months ago I did misjudge the angle
and bumped the tone arm downward when I reached for it. That is, I pushed it
down toward the record before i knocked it backtoward the center of the record.
The record was not damaged, probably because of the .75 gram tracking weight, or
dumb luck! 	
	
Could this have ruined the new stylus?	
	
Heck I did this several times over fifteen years with the other stylus and it
was never affected.	
	
thanks all.

Hi Duane,

According to the Shure website, the N91ED can track from .75 to 1.5 
grams. I have the M91ED/N91ED on my turntable (it shares time with an 
original Pickering V-15) and I always set it for 1.5 grams, which seems 
to be adequate for the old records I, too, am listening to!

Take care.

Michael

Hi All, 	
	
My friend was mistaken. When he opened the box prior to shipping the NOS Shure
M91ED cartridge and N91ED stylus, he discovered it was instead a M55.	
	
As far as I know the Shure M91ED cartridge is not available. So if any of you
know of where I can obtain one, with or without the N91ED stylus, I can use
both, please let me know on the list. Then others who need them will be helped
too!	
	
If any of you know of suitable substitute cartridges for the M91ED, please tell
me about them.	
	
I have no functioning turntable, a lot of vinyl calling to me and I need to find
a way to play!	
	
Thanks guys!

You can find cartridges and styli here, Duane and everybody.  I am
surprised at the number of models available.  The cartridge and stylus links
are on the left menu.   Mark, AA6DX
