Tube Poweramp

-under construction- bagi yang punya ide silahkan isi dulu, nanti saya menyusul...

Apa aja karakter tube yg bs di pake untuk amplifer,pak?

Secara fisik, bgmn kita membedakan kedua tipe tsb,pak? Gold pin-nya ada di bagian mana? Trims

dibagian bawah dan ada tulisannya. :shock:

Hehehehe....jgn kaget,pak :-D

ga kaget kok mr. admin, btw yang sulit dari perakitan tube adalah mencari OT (output transformernya) kalau komponen lain "mungkin" masih banyak ditoko elektronik umum.

Oya,pak. Apakah ada kekhususan tube untuk ampli gitar? Dan brapa lama sebaiknya warming up tubenya sampai stabil & maximal sblm digunakan?

tidak ada aturan yang mengikat "setahu saya" untuk ampli gitar, mengenai proses warming up paling hanya beberapa menit "biasanya tidak sampai jam-jam.an" sekedar menstabilkan elektron dalam tube saja.

apakah beda class, akan membedakan waktu yg di butuhkan untuk menstabilkan elektronnya, pak?

tidak ada pengaruh, jika beda class... yg di warming itu tabungnya saja, sedang modul tidak terlalu memberi dampak..

Apa yang Membuat Sebuah Tabung Itu Dikatakan Bagus ?

The musical detail or ability to reproduce the sound of the instrument is a key factor in assessing a tube for guitar amplifiers. There is no perfect tube available. Each one has strengths, weaknesses and certain factors that contribute to its overall ratings. Usually a compromise is arrived at in the search for premium tone.

All tubes will exhibit some degree of microphonics. Microphonics do not mean that a tube is unusable. You just have to screen them a little closer and determine where they are best suited for use. Input pre-amps are the most sensitive areas of the amplifier. When used in this application most tubes will generate some noise if you tap on them with a pencil during operation. Keep in mind that doing so can actually damage the tube and make it more microphonic or cause it to fail if you hit it real hard. Although they are screened prior to shipment a tube is an electromechanical device and can be damaged during shipment. A microphonic tube will ring, howl or produce general feedback problems. It will be more noticeable at louder volumes or when used in close proximity to a speaker, typically in combo amps. If the tube has good tone at lower volumes and is free from unwanted noise, you use it in a less sensitive part of the circuit, such as tone recovery or phase inverter applications.

Noise is more of a problem than microphonics. A noisy tube will make random popping noises, crackle occasionally or just hum. All tubes have a certain noise floor; this is the inherent background noise that the tube makes in operation. Typically, you will notice this as a soft hiss or "white noise". Tubes designed for high gain can exhibit more background noise. Other components can cause noise problems that may be blamed on a bad tube. Plate resistors are notorious for causing hiss and crackling as they age and begin to fail. A new tube may better amplify these defects, so try substituting another new tube to be sure of the source of the noise.

wew... nice info....

Makasih,pak

ga ada yg ngetik tube lagi yah jarang yg pakai kali ya ?

mahal pak,,,

yg sdh yang type tube yg murah apa ?

tuch CORA mau bukun tube,,tapi masih dalam tahap test...mungkin 2 bulan lagi muncul...

harga berapa tuh, kalau mic 100 / mic 200 gimana ?

harga belum tau om,,mic 100 / 200 belom coba,,
GBU

itu lumayan preamp tabung harganya 500 s.d 680 ribu sekedar tube dibawah 1 juta
