The first Tube amp club of LYN ( i think) and lets gather the tubers up and show the beauty of tube

In general tube amps give a warm sounding mids which audiophiles love to have listening

Vacumm Tube explanation as of Wikipedia's statement @ http://en.wikipedia.org/wiki/Vacuum_tube
QUOTE
In electronics, a vacuum tube, electron tube (in North America), or thermionic valve (elsewhere, especially in Britain), reduced to simply "tube" or "valve" in everyday parlance, is a device that relies on the flow of electric current through a vacuum. Vacuum tubes may be used for rectification, amplification, switching, or similar processing or creation of electrical signals. Vacuum tubes rely on thermionic emission of electrons from a hot filament or hot cathode, that then travel through a vacuum toward the anode (commonly called the plate), which is held at a positive voltage relative to the cathode. Additional electrodes interposed between the cathode and anode can alter the current, giving the tube the ability to amplify and switch.


Advantages and disadvantages as stated @ http://en.wikipedia.org/wiki/Tube_amp

QUOTE
Advantages

    * Very linear (especially triodes) making it viable to use them in low distortion linear circuits with little or no negative feedback.
    * Inherently suitable for high voltage circuits.
    * Can be constructed on a scale that can dissipate large amounts of heat (some extreme devices even being water cooled). For this reason valves remained the only viable technology for very high power applications such as radio and TV transmitters long into the age when transistors had displaced valves in most other applications.
    * Electrically very robust, they can tolerate overloads for minutes which would destroy bipolar transistor systems in milliseconds.
    * Softer clipping when overloading the circuit, which many audiophiles and musicians think gives a more pleasant sound.

Disadvantages

    * A cathode heater is required. Heater power represents a significant heat loss and energy use.
    * Higher voltages are required for the anodes, compared to solid state amplifiers of similar power rating.
    * They are significantly larger than equivalent solid-state devices
    * High impedance and low current output is unsuitable for direct drive of many real world loads, notably various forms of electric motors.
    * Valves have a shorter working life than solid state parts due to various failure mechanisms (such as heat, cathode poisoning, breakage, or internal short-circuits).
    * Available in a single polarity only whereas transistors are available in complementary polarities (e.g., NPN/PNP), making possible many circuit configurations that cannot be realized directly with valves.
    * Valve circuits must avoid introduction of noise from ac heater supplies.
    * Microphonics – valves may sometimes be sensitive to sound or vibration, inadvertently acting like a microphone.

hmm i might get myself a mullard tube to test if the coming rca is not nice..


Added on February 29, 2012, 11:07 pmit is funny how i decided to go with RCA tubes, i thought Grado - USA so... use a USA tube- RCA

since my can is low impedance one, i need a high current amp
luckily the Beijing power tube is good enough, but planning to get russian made tubes later, if wallet allow me to do so

You have to learn electronics and how amplifiers work to understand tube data (or transistor data) for its design application and potential. Not all tubes were designed strictly for audio.
Being knowledgeble about tube amps isn't just about swapping parts and rolling tubes. smile.gif
