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

found tonearm database

mass of my 2 arms is not there, still looking for their mass ___?
........................

interesting how the null points vary for each arm, I've been using my Shure V15VxMR null template for all my +/- 9" arms. 

I just got this as a gift for Christmas, it has a grid to use that will help get any arm right

it's the thickness of a record which is nice when adjusting

Regarding your Victor UA-7082 you can just remember that an optimal Victor top of the line cartridges designed for use with this arm on stock lightweight headshell are as follows (for example):

1) X-1IIe (MM) own weight is 7.5g, with stock shell, wires and screws it’s about 20 g.

Dynamic Compliance 12cu @ 100Hz (*please note than a compliance @10Hz will be at least 20.5 cu)



2) MC-1 (LOMC) mass 8.7g, with stock shell, wires and screws it’s about 21.2 g.

Dynamic Compliance 8cu @ 100Hz (*please note than a compliance @10Hz will be at least 13.6 cu)


So i think you can use any cartridge on 12g headshell with dynamic compliance from 13cu to 22cu @10Hz according to Victor philosophy. There are low and mid compliance cartridges! For higher mass headshell/cartridge combo with lower compliance cart you need a subweight for the arm.

I don’t think you will find any headshell lighter than 9g for use with higher compliance cartridges.

Buy Hi-Fi TEST LP to measure actual resonance with your own arm/cartridge if you’re so worry about it.

Many online calculators are incorrect, you’d better use a record to check tonearm/cartridge resonance, you will see when they are shaking.


P.S. And stop buying mediocre cartridges if you really want to hear the potential of those tonearms.

I think that its lift is worthless

I've seen two different armlifts made by Lustre for 801 series. So they tried to improve.  

Your right,

This morning I ordered a Jico Shibata for my Shure V15VxMR to get it going again. I've been mad at it due to the brittleness of the stylus I broke years ago. This one is boron, caution will be exercised.

As a test I cleaned a really dirty noisy record last evening, waited till properly dry, it was surprisingly noise free with the AT440ml, I just need to play something in good shape while a really dirty one is drying. 

So I will have those two: Shure shibata with brush, AT microline no brush. Both track 1.25g

Now: UA-7082 arm that is coming: keep Z1S, put a shibata in it, or, new victor cartridge with new shibata?

One of my test records has all the resonance test bands.

Dear @elliotbnewcombjr : You need to make your job because you posted two threads and in one of them ( before in this ) you asked for tonearm effective mass and I gave you the links about and seems to me that you did not read it, go figure ! ! If you don't read your threads posts you are losting valuable information and that's why you are asking here for the second time:
