Integrated Amplifier Explorer 150 SB de Kora


The Explorer 150CSC is the latest Kora hybrid integrated and the first of a new line.
A powerful 2 x 150w (4ohms, 100w @ 8 ohms) amplifier that is at the cutting edge of tube and solid state technology.
- Integral remote control.
- Protection & temporisation by microprocessor.
- Input & output sockets gold plated 24 carat & teflon isolation.
- 4 inputs + monitoring loop & direct access to preamp & amp.
- Headphone socket. It used a 6922 double triode for the preamplifier section and a ECC99 from JJ Tesla , driver for the power section. This new version include the CSC technologie develloped by Hi End Audio Technology
- Power amplifier and preamplifier totally independant.
- Preamplifier : double triode 6922; 20dB calibrated gain; no feed-back; independant output; <0,1% distortion (harmonic 2); input dynamic >+12dB; input impedance 1M ohm; output impedance < 1K ohm.


- Amplifier : Tube & Mosfets hybrid - 2 x 150w/4 ohms & 2 x 100w/8 ohms; drivers stage ECC99 by JJTesla; power stage by complementary Mosfets; frequency band : 0,2Hz to 200kHz; distortion < 0,3% full power; only 3dB feedback; output impedance < 0,1 ohm; input impedance > 75K ohms.
