Product Description
The main factors affect the sound quality of vacuum tube amplifier
1. Single-ended and push-pull circuit At the end of the power amplification, amplification of push-pull is easier to get high power output, because push-pull is a vacuum tube amplifier "+" signal, a vacuum tube amplifier "-" signal, and then superimposed, so large distortion. Single-ended amplifier is a vacuum tube amplifier "+, -" signal, does not need the signal superposition, therefore less distortion. The sound Single-ended than push-pull good, especially in some minor details. However, Single-ended is difficult to obtain high power output, with vacuum tubes of the same type, Single-ended can do 10W, while push-pull is easy to do 30W, Single-ended to obtain large power will have to pay more price.
2. push-pull end power amplifier of vacuum tube different connections
push-pull the end of the power amplifying vacuum tube usually have three connections: triode form, super linear form and standard form. Theoretically speaking, the triode form by minimum distortion, output power is minimum; standard form get larger distortion, power is also the maximum; between super linear form between.
3. Affect the power transformer and output transformer of sound
High quality vacuum tube amplifier inseparable quality transformers, power transformers currently technically no trouble, the output transformer is the decision of the vacuum tube amplifier sound quality is the key. Because regardless of the output transformer selection is good, how sophisticated technology, both methods exist to avoid leakage inductance and stray capacitance components, resulting phase distortion. Output transformer as inductive element, to the transmission signals of different frequencies have different inductance. Therefore, the output of the transformer will be different in different voices lead. No high-quality output transformer, other aspects of the production of better quality vacuum tube amplifier is also meaningless.
