Features of this machine: 1. Well-designed appearance, adopting modern industrial product design ideas, simple and elegant, internal point-to-point wiring, manual welding. 2. Using four KT88 vacuum tubes of PSVANE with customized parameters as AB1 push-pull amplifier. 3. The preamp uses two 6H2C and 6N7P vacuum tubes. 4.

A KT88 push-pull pair in class AB1 fixed bias is capable of 100 watts of output with 2.5% total harmonic distortion or up to about 50W at low distortion in hi-fi applications.

The KT88 has an absolute maximum anode dissipation rating of 42W and is designed for use in the output stage of an a.f. amplifier. Two valves in Class AB1 give a continuous output of up to 100W. The KT88 is also suitable for use as a series valve in a stabilized power supply.

2011年11月17日 · AB1 class amplifier is operating in class A when the used power level is less than maximum. The transition between A and AB1 takes place depending on the used power level, bias, load impedance etc, but it is not sudden. You can assume that a 50 W KT88 AB1 amplifier works in pure class A when the power level is below 25 W.

Summary The KT88 beam pentode is primarily utilised in the output stages of audio amplifiers but can also be used as a series regulator in a stabilised power supply. With an absolute maximum anode dissipation rating of 42 watts, a pair in Class AB1 …

With an anode to anode load of 4,000 Ω and 550 Volts on the anode a pair run in ultra linear AB1 will deliver 100 Watts at 3.5% distortion. With 425 Volts on the anodes and a load of 6,000 Ω the pair will generate 50 Watts at 2% distortion.

KT88 is a beam power tetreode, its anode limited dissipation power is 42W. In the audio amplifier, the power can be 100W when it is used as push-pull class AB1 with double tubes, it can also be used in electronic voltage regulator circuit. KT88 is similar with CV5220 and 6550,they can be replaced by each other. Direct Interelectrode Capacitances.
