Looks good Guy.

Dont forget to make the needle follow a straight
line that goes through the spindle.You may have to swing the
glass tube arm a bit to make them parallel to each other. You can adjust
the arms length a little to make it work if you have to,
but it should be very close.

Hi bacobits.
If you want to hear it, you will have to come on planet Vietnam. :lol:
I have ordered from Amazon a Pro-Ject phono box DC
that will be delivered to my wife's nephew in Seattle,
then his father will bring it on his trip to planet Vietnam in October,
therefore, I have to be patient and wait a little more,
that will give me time to complete the installation/adjustments
of my PDR linear arm.
So, you should buy your space shuttle ticket for planet Vietnam
for end of October to arrive just in time to have a listen to my super TT :lol:

Thanks.

Hi all.
The set up is almost completed.
This is what I did:

With an aluminium coat hanger I did a support contraption for the (hair size)
wires from the junction box to the cartridge.
Hopefully the wires won't pull on the arm.



An over all view.



It was not easy to set the weight at 1.8Gr. I had to make sure the tiny wires did not pull or push on the cartridge to change the weight.



Nest step will be the Pro-Ject Phono Box MM pre-amplifier that I will get next month via a relative from the USA.

Patience.

Guy 13

Perry, I wonder how many times you dropped the ball bearing on the floor.
I must have dropped them a zillion times...
It's like they were alive and did not want to do their job.

A zillion and one..... :lol:
Now that you have it more or less set up, the ball
bearing chasing should stop.

Have you tried a record yet?
You wont hear anything with out the amp,
but you can see if it tracks without
interference from the wires.

Clean the tubes with a Q-tip and a little alcohol
if you have any.

Hi Perry.
You beat me on the BB chasing. :thumb:
I have not tried any LP yet,
because I did not see the use/purpose of doing it
if I can't hear anything,
but you brought up a good point,
I will try today or tomorrow depending on my busy schedule.
Q-Tip (Here it's called differently) my wife can supply to me,
without her, the Vietnamese Q-tip factory with close the doors.
Alcohol not sure, I might use instead acetone
which is more readily available here.
Will get back to you with more...
Thanks

Guy 13.
I really have to more the arm slowly and delicately,
otherwise, it fall off of the rail.

Hi Guy,
Looks like a good antenna.  Just kidding I know you don't plan on leaving it like that.  I thought I'd show you an example of braided tonearm wire.
http://www.vpiindustries.com/tone-3d.htm

It might take a little experimentation to see how short you can make the wires and where to start braiding.  Good luck with the project, it looks like a good one.

Hi neo.
Of course that set up on the picture is only temporarily,
I will refine the set up as I made a few tweaks here and there
to improve the sound.
I did try that setup as is, but the cartridge's needle was jumping from
one sillon to the other.
But it did sound fairly good.
Now I am getting back to my man's cave, which I call my penthouse
and try to make the set up sound as good as I can.
I will report later on on my success  :thumb: of failure  :cry:

Guy 13

By the way, I did try my set up with my Bellari VP-129 phonopre-amplifier
and I had a little hum and a little interference when the volume control of my amplifier was at 3pm.
I will get my Pro-Ject phono box MM next month, therefore, the final results will only come next month.
Patience.

Hi all.
At last, at long, long last...
It's finish, completed and working fine.
That was something laborious for a guy like me with it's hands full of thumbs.
All the adjustment are made as per Perry and others.
THANKS ALL !
(Especially Perry for his wonderful gift. highly appreciated.)
It was time consuming
and needed a lot of patience for a guy like me.
But it's done and now rewarding.
I've played a few vinyl and it sounded good, why not excellent?
Because I had to still use my Bellari hummer and FM receiver unit.
Now I will not play anymore vinyl because of the BB (Bad Bellari)
and I will wait for my Pro-Ject phono pre-amplifier.
By the way, the Pro-Ject can operate on a walwart 120V input 18V DC output
or one 12VDC battery and one 6 VDC battery in series.
Therefore I should avoid at least the hum.
Thanks, thanks, and one more thanks.

Guy 13

Too bad I cannot use the plastic cover,
but I found a transparent plastic bag that will just rest over the table
and that's fine.
Each year that pass by, I am less demanding
and each year that pass by, I have less money to spend on audio stuff.
That's why I am satisfied with what I have now.

Hi Perry,
even if my PDR linear arm did not sound better than my Rega RB301,
which is not the case,
it sure look more impressive, very different and is definitely a subject of conversation
and maybe also jealousy.

Hi Nick77
It's not:
We don't believe you,
it's more like: You don't believe me.
Well if you need picture(s) have a look at
Reply # 144
The only difference is that the tiny wires are now tied together
and I did some tune-up that cannot be seen on the picture.
Well, believe me or not... That's. what it is. :lol:

It will be fun to see it tracking in the middle of a record when you'll all setup. Hope your new pre arrive soon.

Hi Nick77
Why do you say it would be fun to see it tracking in the middle of the record?
How about the beginning or the end of the record?
Why especially in the middle of the record, what's so special about the middle???
By the way, my phono pre-amp should arrive in the second half of October.
Patience.

Hi Nick77 and all.
I will have my new Pro-Ject Phono Box DC purchased from Amazon this coming weekend via a relative that will leave Seattle on the 25th and if I am luck and his plane does not crash  :nono:
I should have it during the weekend or early next week.
I am very anxious because it's been a long time since I did not play any vinyl
and that my PDR linear arm is been set up and ready to scratch my vintage collection of vinyl.
Little more patience.

Hi all.
At last, at long long last...
I just go my Pro-Ject Phono Box DC that I've bought from Amazon for 149 USD and that was brought on planet Vietnam by a relative from Seattle.
(No custom tax - no transport fees.)
It's installed and running, however I still have a very faith hum,
but no FM interference, that an improvement over my previous Bellari VP-129
Sounds good, but I suspect that the output of the Pro-Ject is not 2 Volts,
my Decware SE84C+ need a minimum of two volts to give it's full 2wpc.
I will try to swap the walwart (18 VDC) for some batteries. (One 12V + one 6V should do the trick) and see if I still have a residula hum.
Other than that the PDR linear arm works good, I still need to make some fine adjustments, you need to do everything very slowly and carefully otherwise you have to run after the ball bearings that fall off of their glass tubes location.
Thanks to Perry for the PDR linear arm.
I will also have to find a way to protect the whole thing from dust, bceause planet Vietnam have so much dust that they could fill the Grand Canyon with it.

Will update of the final result.

Guy 13

I was surprized to see how small it is.
Could almost fit under the turntable.

Finally, nice enjoy!

Unshielded interconnects can cause some hum.
Wrap some aluminum foil carefully on the tone arm interconnects at the Pre end and interconnects
from the Pre to the Decware. See if it quiets down completely. Sometimes no ground helps too.
Some times here on a non polarized plug,  turning the wall wort plug around in the outlet helps and sound better.
But you may be using something for 220v?

Hi bacobits1.
Maybe you need new reading glasses. :lol:
I wrote several times that my interconnects are shielded Signal Cable.
I have to try to turn around the walwart,
I did it with my Bellari walwart
and did not have any improvement, but I will do it any way just in case
and because it cost nothing.
My Pro-Ject walwart is 120V. and it's plugged on my PI Audio Majik Buss.
Yesterday I was fooling around trying different things to try to illuminate completely the hum.
I will do more fooling around this evening.
