Tonearm ...... Acos Lustre GST-801 ..... Yea/Nay


Acos Lustre GST-801, claim to fame is magnetic stylus force and magnetic anti-skate.

Hopping about, getting ready to pick the rear arm of 2 arm deck. Use for existing Shure 97xe and V15VxMR, both with their dynamic stabilizer brush, and AT440ml (no brush), and NEW Mono Cartridge.

I did see and read your post, (and everyone's) thanks. You have been quite helpful as have others.  I clicked both links, they didn't go directly to something, I hopped around, searched, didn't work out.

This project grew and grew: from 1 longer arm, (presumably use existing cartridges), to big TT, dual arms, then, use one arm for Mono, rearrange the whole system, add new stable legs to the equipment rack, order a tempered glass shelf.

Then do a better job cleaning my dirty lps, add a safety lift, get a new stylus for my Shure cartridge, resurrect my AT440ml, probable stylus/cartridge change on the 7082 when it gets here (TT shipped today from Canada).

this is complicated stuff, there are 3 threads

1. 12" arm???

that thread got me to the large Plinth JVC and to two arms.

2. Compliance/Cartridge for new specific Long Arm JVC 7082? which I bought, and 7045? (which I presumed I would buy).

Along the way I learned the 7082 is kind of heavy for my existing cartridges, so I looked for a lighter arm, found the Acos.

I further learned there is a lot to learn.

3. Acos Lustre GST-801 Arm? Separate thread because people who know about it may not be involved with thread 1 or 2.

Thanks specifically to you finding the one I bought, I got a better, more complete arm and better price.
...............

And, mixed in, which new MONO cartridge? use existing cartridges? new stylus for existing, new stylus for included JVC Z1S?

I am still a novice about compliance and resonance, and 

I found a chart about 7 million arms, the mass of my 2 arms is not listed.

Holidays almost over, my research has been sporadic, people who own these arms know more, so I just got lazy and waited.
..........................................   

to recap, here's what I was confidently able to order after help in the 3 threads:

a. New to me Dual Arm Heavy Plinth JVC TT81 including long arm 7082 with Z1S cartridge, with Din Cable, with power transformer

b. New to me 9" GST-801 arm all parts present, din cable included

c. New Stylus for Shure V15VxMR body (learned about JICO here).

d. New Grado ME+ MONO Cartridge. Learned about 'real mono' here.

e. New full size alignment disc with info to locate any arm/align any cartridge, variations of null points.

f. New record bath with drying rack (drying easily was the missing link for me).

g. New tonearm safety raiser, didn't know they existed.

h. New digital tracking gauge, goodbye Shure See-Saw.

i. improved rack arrangement, new stability, new big glass shelf.
...........................

Just waiting to make final decision on Cartridge/Stylus for 7082 arm.

being a bargain hunter, with help here, all that: $2,500.

Let's not forget, agreeably cancelling the TT from Japan, finding one in Canada, having seller repair counterweight arm portion which I learned about here.

I'm real glad I joined this forum.

@elliotbnewcombbjr : Well,you need at least alittle of common sense.In the first link/this one:

https://audio-creative.nl/platenspeler/hoe-kies-passend-element-platenspeler/attachment/calculator-effective-tonearm-mass-2/


appears in the left up side a little " box/squaer " in blue color along a little tonearm picture. You need to make click on that box and there is the calculator.

Here in my country people say: " you want it " peeled " and in your mouth ". ! !

GST801 as mentioned is a fine piece.   I think I may have the original tonearm lift, and that is the weak point in this, which is not a big deal.   The original headshell is not that light mass wise.   Without wires and hardware is 9.2 grams.   Will be a 15 gram or more so if you add up the rest.   As far as the additonal weights those can easily be made in a machine shop if that is holding you back, that is what I did.    Great arm, won't be releasing it anytime soon!
