Diamonds are said to increase personal clarity to help one see things clearly as well as be straight-forward and honest. Supposedly, the higher quality the diamond, the better it is supports these qualities.

Some lists consider these stones to be your birthstone. (Birthstone lists come from Jewelers, Tibet, Ayurvedic Indian medicine, and other sources)

No ordinary person, full imagination and originality, shy and reserved, ambitious, proud, self-respect, hungers for new experiences, sometimes nervous, many complexes, good memory, learns easily, complicated love life, wants to impress.

The moon’s phase on the day you were
born was in its last quarter.

Deskripsi:

Filament Supply & B+ Supply

Rangkaian power supply untuk filament dan B+ sama persis dengan rangkaian untuk preamp srpp di project sebelumnya. Hanya R di pi filter yang beda, karena arus yang dibutuhkan 2 kalinya (dibanding srpp).

Pre-amp:

Disini masih menggunakan tabung 6n1p dari Svetlana.

Topology persis dengan topology Foreplay dari Bottlehead, yaitu grounded-cathode diikuti oleh cathode-follower. Topology ini memiliki impedansi output yang cukup rendah, sehingga bisa drive power amplifier tanpa takut kedodoran. Tetapi kelemahannya adalah PSRR yang rendah, bila power supply tidak bersih, ripple/hum dari power supply bisa mempengaruhi reproduksi suara.

Uji dengar:

Untuk uji dengar kali ini, digunakan satu saja MF-A1 punya saya. Susunan peralatan:

–[Nakamichi CD-4]—[DVD Pioneer DV393]—[pre-amp ini]—[MF-A1]—[loudspeaker]–

Masih menggunakan 3 CD referensi yang sama; Zhiao Feng, Susan Wong dan Jheena Lodwick. Referensi DVD dipilih “Into the Blue”.

Dari uji dengar dapat diambil kesimpulan, bahwa dengan pre-amp tabung foreplay ini, reproduksi suara lebih tebal dibanding SRPP, detil suara yang tadinya tipis jadi lebih berbobot, mid-low lebih detil.

Sekarang memutar referensi keempat; Into the Blue. Jessica Alba memang bener-bener sexy abiss. Lahh … suaranya gimana? Nanti lagi test suara, sekarang nonton si Jessica Alba dulu dehh … heemmmmmmgghhh …

You’ve Got A Friend

When you’re down and troubled
And you need some loving care
And nothing, nothing is going right
Close your eyes and think of me
And soon I will be there
To brighten up even your darkest night

You just call out my name
And you know wherever I am
I’ll come running to see you again
Winter, spring, summer or fall
All you have to do is call
And I’ll be there
You’ve got a friend

If the sky above you
Grows dark and full of clouds
And that old north wind begins to blow
Keep your head together
And call my name out loud
Soon you’ll hear me knocking at your door

You just call out my name
And you know wherever I am
I’ll come running to see you
Winter, spring, summer or fall
All you have to do is call
And I’ll be there

Ain’t it good to know that you’ve got a friend
When people can be so cold
They’ll hurt you, and desert you
And take your soul if you let them
Oh, but don’t you let them

You just call out my name
And you know wherever I am
I’ll come running to see you again
Winter, spring, summer or fall
All you have to do is call
And I’ll be there
You’ve got a friend
