click to view full size image K4040   -   STEREO TUBE AMPLIFIER / CHROME VERSION, For most of us a high power tube amplifier is unaffordable. This kit changes that, so that everyone can enjoy that sublime "tube sound". The sound of tubes has never been surpassed. In the course of developing this amplifier, special attention was given to the housing so the tubes are on display in a way that is very pleasing to the eye. Ultra-linear and over-rated output transformers (toroidal) are used to guarantee a rich bass response. To extend the life of the tubes, the amplifier is provided with a power on delay, so that the high voltage is switched on after the tubes have warmed up. Output power: 2 x 90Wrms music power for loads of 4 or 8 ohm. Power bandwidth: 15Hz - 40kHz (-3dB ref. 50W). Frequency range: 8Hz - 80kHz (-3dB ref. 1W). Harmonic distortion: 0.08% (1kHz / 1W) / 0.7% (1kHz / 90W). Signal-to-noise ratio: > 105dB (A-weighted ref. 90W). Channel separation: >75dB , input impedance: 34Kohm. Input sensitivity: 1Vrms at 95W. Damping factor: >10 (100Hz). 37.5 lbs sh. 16.7x5.1x13.8. Drop shipped from Texas. List Price, $2428.00; Our Price,
