[#101] Cheap turntable appreciation haha    
Haha


U used knift... I use lazy hand electric grinder.. Haha

I read most of your past post with your creation haha

I add the side weight is for counter act the increased anticlockwise tendency when using heavy cartridge with the sme arm which designed for light weight cartridge... And it works... Haha high is higher.. Bass is tigher... Haha


For the arm tube.. I wish to alter the tone.. Haha.. And it is haha

For the back copper counter weight sleeve.. For look, for adding weight... And wish to alter the tone.. Haha
.. Does it alter the tone.. No idea.. But I can use heavy weight MC now
. Haha


The effective mass of the sme arm is now about 6.8 without headshell.. Was less Than 4 gram

There comes another one from Accardo.

i forget how's the original sound.. but from memory it was really quite nice ...rich.........


haha fun things to share, after playing around some wood with SME arm..... when i listen to some drum track

it is much easier to tell the relative positions of the Cymbal...hi hat and the bass drum..etc.. i guess it mainly due to the added side weight

I also have the same Accardo's Reissues from Philips. I believe it's issued with the mind of Hong Kong Audiophiles encouragement.

I didn't buy that record and to be honest with you. I didn't know even know this is such high price record back then. It was a gift from one of my acquaintance I met through R33 after I gave him some of my records. Again, I know of nothing about the original recording in terms of sound and quality. It seems pretty good for me with this reisuue anyway.

The first encounter of this piece of music was actually a recording of Sir Neville Marriner under Argo Label. I have about 7 copies of this LP, first pressing, later pressings, mostly bought from car boot sales, no more than £2 each from all these years.

Hear the two versions and which one do you prefer?

Sir Neville Marriner



Salvatore Accardo

For fun

Haha...

I have some magnetic field mearuement apps

I take mearuement here and there.. On th e platter for a few DD and a belt drive.. And the lenco, to check rather it is strong magnetic field presents at the surface of the platter which may affect cartridge preformance... If it is.. Strong enough.. It will affect

A few finding.. Worth to share


Let's say... The room surrounding is around 35ut


At the top of the proac speaker.. It is 250ut

At the top of the thorens td126 belt drive.. It was same as the surrounding.. So it is good


At the lenco.. At right hand side of the platter.. Ie the cartridge contact area.. It was also around 35ut

At the left hand side.. Of the lenco platter.. Above the motor sitting... It was about 76ut


At above the micro seiki DD7... Omg.. It is 220ut


At above the kenwood.. One side is 35ut.. One side... Is 95ut.... Haha



Which lead me to wonder.. Soemthing can be done... Then I think of making a MU metal thin sheet record mat...

Haha.. I find those material at Round 0.3 mm thick at cost about rmb120.. So I can cut one myself... Why 0.3mm..but not 0.1..etc..or 0.5.... Haha.. From guess.. Thickness I can cut nice.. And still feel cheap.. Lol

There are always.. Was always someone may had the same idea or did the same thing.. I google it... It is... Haha.. But I did not read too much of the sharing yet...


It will reduce the residue magnetic field by using a mu metal mat.. But is 0.3mm..etc..enough..etc....but by how much... Haha no ideA

For spending rmb120.. Worth to try.. Haha... Little things I can do.. By physics..in principle.. Things will be better.. Haha


We build a tower by trillion of sands.... A good system also.. Demand... 1000...little things to be done to get there too...

Haha I beleive...... Haha...

Most important.. I am boring..haha..wprk at home haha


For before and after..comparison test

More on Argo.

I love scared and mass music and the choral singing would just lift my spirit though I am not a Christian.
