#SOUND REFERENCE KT88 TUBE POWER AMP DRIVER#

Selection of Japanese high-grade ALPS motor potentiometer.Įasy installation of the plug-type vacuum tube shield There is a power tube current control button and an electric meter dial. It has a phono stage input function, which can be connect directly with a MM Vinyl turntables It has a pure power amplifier ans it can conncet with an independent pre-amp's signal input. The ultra-linear connection is suitable for the big scence, the sound is more open and lively.

Use special high selected KT88 tube as push pull power amp lamp,providing switch for the triode connnection and ultra-linear connection modes.The triode connection mode is more suitable for the voice and the sound is more soft, delicat as well as nature. Use 2X12AX7 and 2X12AU7 as amplifiaction, Using a customize Z11 core toroidal power transformerĪmplification and drive part use SAR4 rectifier. Using two high quality and wide frequency response EI output transformer Storage conditions: Temperature: -20 ✬ ~ 70 ✬ Humidity: 20% to 90% Working conditions: Temperature: 0 ✬ ~ 40 ✬Humidity: 20% to 80% Harmonic distortion: 1% (1kHz) Frequency Machine: 15Hz ~ 30kHz (-1.5dB) Input Sensitivity: 280mV 520mV (pre input) Output balance of the left and right: <0.5db Headphone output power: 300ohm with 900mW, use 270 like a basic divide to calculate the output power, for example 270 / 300ohm =0.9w for 300ohm headphone, 270 / 32ohm = 8.5w for 32ohm headphone The midrange was liquid, exceptionally relaxed, yet reproduced with first-rate transient and harmonic definition.Speakers output power: 25W + 25W (RMS triode mode) It has a real beauty of tonal rendering coupled with fine inner dynamics, achieved without any exaggeration of drive or presentation. Jadis JA80's performance from the upper bass to the mid treble can be described as eminently musical. The JA80MKII has this ability to make sense of the musician's intent that separates the Jadis from much of the audio pack.' Alan Sircom - HIFI+

'A pair of JA80MKII have one of the most holographic soundstages out there, with its outstanding depth and even great height. When switching from KT150 to another type of power tube such as : E元4, 6CA7, KT88, KT90, KT120 & 6550 a small modification has to be made inside the unit. The frame, in 316L non-magnetic stainless steel, does not influence the electronics and renders the device unsensitive to external disturbances. The device is assembled with conventional cabling 'point by point' and uses a silver / copper tin solder. Gold connections assure a faithful broadcast of the signals. Heating the tubes is by alternate current with balance and noise reduction. The filtering of the high voltages is assured by high capacity capacitors. The power transformer is oversized for a better dissipation of heat and vibrations. The cathode circuit is protected by an individual fuse. The output transformer, guaranteed for life, allows an adaptation of impedance from 1 to 16 ohms.

#SOUND REFERENCE KT88 TUBE POWER AMP DRIVER#

The function phase shifter is insured by a triode double ECC82 and the function driver by an ECC83. The MkII version brings the compatibility with the KT150 pentodes. It can work with various types of penthodes: KT120, KT90, KT88, 6550, 6CA7 or E元4. It works in a 'push-pull' configuration with triple load and autobias. It is the first amplifier created by the JADIS in 1983 it has been upgraded several times but remains the flagship of the brand. The JA80 is a power amplifier working in pure class A.
