Sony PS-LX350H the usual questions.......

Post by jsmiddleton4 » 28 Jul 2005 15:20

Good morning,

I've just picked up a fairly new LX350H for 34 dollars locally. Plays well and for 34 dollars it was a perfect match for my need. Converting musical LP's, some regular music LP's, to digital. Yes I know there are better TT's. But price/value/application and this was a good solution. Totally manual, gets the job done.

Have searched this forum, the library, etc., for any information on the TT. Still searching the web. Have some simply setup questions and while I've found a ton of information, thanks for maintaining the forum, I haven't found this particular TT.

The manual provides no information on stylus overhang. I have read the several TT setup threads, gone to the links, d/l the printable protractor guides, etc., so I can setup the LX350. But I am going to update the cartridge. So I'm looking for advice, links, etc., on new cartridge for the LX350 as well as any information on overhang for those new cartridges. I have older decent Kenwood receiver that has phono circuit so I'm good to go there. Was looking in the 60 to 100 dollar range for the cartridge.

Replacing the belt. Was just going to order from the Needle Doctor, etc., standard belt. Any options on belts that I'm not aware of for this TT?

I'm a recycled TT user. Had the discwashers, resonant absorbing feet, etc., moderately priced stuff in the 70-80's of course. Some of it coming back, some of it not. So I appreciate the help.

Record cleaning. So where are we at now? Simple brushes with some anti-static property about the best general solution?

Jim

Sony manual says

Tone arm effective length is 220mm
Overhang is 10mm
Usable cartridge weight is 6 to 10 grams

Okay, 10mm from what to what?

Hi,
The manual provides no information on stylus overhang.
The manual makes no mention of aligning the cartridge at all, even in its section on cartridge replacement! Luckily the manual does state the overhang (as you mentioned) as being 10mm. This is the distance the tip of the stylus should overhang the spindle centre with the cartridge square in the headshell (any cartridge, not just the original). If the table came with no guage for setting this then I would try a universal Baerwald two point protractor. One can be downloaded and printed out from the library here, or Enjoy the Music do one for the price of a self addressed stamped envelope: http://www.enjoythemusic.com/freestuff.htm
Any options on belts that I'm not aware of for this TT?
Only that pattern belts arent always as good as original. They generally list the closest length to original that they stock and this may or may not be ideal. I'd always check the cost of a genuine replacement first as they are sometimes cheaper than aftermarket!
Simple brushes with some anti-static property about the best general solution?
IMHO you can't beat a carbon fibre brush for day to day cleaning at just a few pounds/dollars.
Was looking in the 60 to 100 dollar range for the cartridge.
There are quite a few threads here and over at the Vinyl Asylum where budget cartridges are discussed. I wouldn't invest too much as your table may be the ceiling here, but something like an AT95E or AT110E should work very well. At their respective price points they are unbeatable :wink: (Grado fans may disagree!)

JaS

TT Setup

Post by jsmiddleton4 » 28 Jul 2005 18:13

Thanks for taking time to reply.

I have d/l the "Steve's free protactor" setup pdf file. Looked at them all. It gets a bit confusing. So if I remember correctly then, when the cartridge is square it should be forward/backward enough so that when it is over the center of the spindle the tip of the stylus/needle should extend 10 mm beyond the spindle center? Is that correct? That's what that means?

There is one of the protractors that includes the 220mm arm length. Looked at too many to tell you which one off the top of my head. You can square the cartridge/ set the arc correctly, etc. all with one protractor. At least it looks to be that way. Of course when I set my last turntable up I didn't have trifocals! And I don't quite understand where you place or reference the protactor on the platter. If I'm using the head/cartridge prior to adjustment to line up the adjustment tool, that's the blind leading the blind. So how does one place the protactor on the platter so the protractor is properly aligned to be the reference?

All I remember doing in the past is using the little plastic overhang guage, popping in the cartridge tightly enough to be stable but still movable, holding the head with the cartridge carefully into the overhang guage making sure it was snug against the back of the head/plug-in side, lining up the stylus needle point with the guage, tighten the little screws.

Seems like the protactors are more accurate but sure are more complicated.

Thanks again
Jim

I searched quite a bit more. Only found folks complaining that there was no overhang guage, didn't find any solutions in those threads. I did email Sony support. Wonder if they'll reply.

Will look at those cartridge suggestions.

Hi,
Some high end arms come with a simple overhang guage, but these also come with a foolproof way of mounting the arm at the required distance. On decks like the Sony that are mass produced with a dedicated arm an overhang guage makes alot of sense. However, Sony may not have chosen a particularly low distortion alignment method so the use of a generic Baerwald two point protractor would probably give better results. However, when using an alignment method other than original you may need to offset the cartridge in the headshell.

If you just want to set the overhang at 10mm this protractor is ideal, notice the overhang guage with 10mm arc: http://www.docethifi.com/alignmentprotractor.pdf

Office type A4 paper hole punches are around 7mm which is OK for most spindle sizes so as long as you can print out the protractor accurately you shouldn't have too much trouble making the neccasary hole.

If you want to use a Baerwald protractor like seb's 'stupid protractor' in the library, the following method is pretty straightforward:

https://www.vinylengine.com/manuals_ton ... tors.shtml

(1) mount the cartridge in the centre of the slots

(2) place the stylus tip on the outer point (b) and slide the cartridge back and forth in the headshell so that the sides of the cartridge are parallel with the alignment grid when the stylus is exactly on the point.

(3) rotate the protractor and place the stylus tip on the inner point (a). the sides of the cartridge should align with the grid. If not then again try moving the cartridge back and forth in the headshell. repeat steps (2) and (3) until alignment is OK at both points

If you can't find a position where the cartridge sides align at both points you may need to turn the cartridge so that it is not square in the headshell. repeat step (2) but instead of sliding the cartridge back and forth, rotate in the headshell until alignment is reached. now repeat step (3) as before. Repeat both steps until alignment is OK.

Another method (and protractor) can be found here:

Hope I'm not making matters worse :wink:

JaS

Thanks

Thanks for all the resources. I spoke with Sony, went all the way "up" to product specialist. They were clueless. Product specialist said to just mount the new cartridge so that the holding bolts go all the way to the back of the slots on the shell head and I'd be "ok". The problem of course is I am talking to people who have never had a turn table or set one up. What used to be a fairly common term/idea "stylus overhang" means nothing.

The second level service tech pulled up the service manual however. And the service manual uses the 10mm over hang as the "official" measurment. I was already planning on putting 10mm circle out from center of any of the protractors. Now with your link I don't have to. Plus I now understand the reference point so that the protractors are the credibile guage, the line that goes to the center of the pivot point of the back of the tonearm. So beyone the 10mm overhang past the center of the spindle, Sony has no other information.

You've provided a great deal more help. Thank you.

And by the way, Sony belt at Sony is about 6 U.S. dollars. Third party ones are three times as much around 18 U.S. dollars. So you were right about that.

A bit confused

Post by jsmiddleton4 » 28 Jul 2005 22:57

Okay now I'm a bit confused. I've looked at all the protractors until my eyes are crossed.

I think I can get the cartridge square in the shell and then use the 10mm overhang gauge. That doesn't seem to be too complicated.

The problem that confuses me again is when I look at all these protractors, what reference point do you use to set them up so that they are the reliable reference. I think only one of them has the line that you use to sight the pivot point of the tone arm. When I look at the pictures of the high end Thorens ones, they have a point that sets right on the pivot point of the tone arm and then on the spindle of the turn table.

That makes sense. Also cost a lot of money. Some of the "print your own" protractors, I don't see any way to set them so that I know the alignment grids on them are in fact the authority.

Hi,
With a two point protractor you don't need to align anything with the pivot point, just move the protractor and the arm so that you can place the stylus on the marked point then see if the cartridge sides are parallel with the reference lines on the protractor. If you move the catridge in the slots so that at both points the cartridge is parallel to the reference lines you are in alignment :D

Fairly simple then?

Post by jsmiddleton4 » 29 Jul 2005 01:04

So you use the two markings-patterns to eliminate the variance having the protractor in any old place, I'm exaggerating a bit there of course, would create if you just had one pattern?

Trying to get this in my head. Its really pretty simple then isn't it? So the two sides of the cartridge and the point for the stylus become the orientation coordinates to get the reference pattern in the right place?

Starting to sound like Stargate here.......

I think so

Post by jsmiddleton4 » 29 Jul 2005 14:20

Yes I think I have it. But only because you took the time to help, I read the resources here like the "sticky" on setting up the stylus, took advantage of the links which had information and the free resources like the protractor templates.

Thank you again both for your help and for those who maintain this site.

I'm looking forward to getting everything setup. I'm in Phoenix, Arizona and its HOT. We're heading north for the weekend and I'll be setting everything up later next week-next weekend. So I'm looking forward to going back to the 70's!

Listening to Johnny Mathis....

Post by jsmiddleton4 » 05 Aug 2005 02:26

Yes, if you can believe that. Thought his vocals and orchestra would be good way to check the turn table.

Did all the setups, etc. Using any of the cartridge alignment tools/overhang gauges moves the cartridge (its the Sony ATN3600LXE which looks to be supplied by AT for Sony, and it is LONG) all the way back in the slots on the head. The stylus is on the cross hairs of the grid, etc. Sony says the overhang past the spindle is suppose to be 10mm. I'm not even close! But, it sounds great.

Jim

By the way, I did notice that the cartridge, which was square in the shell, when I get it lined up with the grid, etc., the cartridge isn't exactly square in the shell any longer. It fits in the grid parallel to the lines, all that jazz.

Issue or normal?

Jim
