Excellent condition with original packaging, with KR 845 valves preamp.


The highly regarded 845 power triode and is capable of delivering up to 20 watts of power into a 4, 8 or 16 ohm load. The zero-feedback circuit incorporates an extraordinary single-stage driver topology employing two EL803S power pentodes operated in triode mode. The driver stage is so powerful that it could (theoretically) drive a loudspeaker with ultra-low distortion on its own. The amplifier is entirely hard-wired, while every detail of the internal construction has been given carefull attention to ensure reliability and ease of service. The sound of our “flagship” is of utmost refinement and will easily measure up to the expectations of even the most critical and experienced music enthusiast.Of special importance are

several key design features which provide

exceptionally noise-free performance even

when highly efficient speakers are in use:DC heating is provided for the power tube, whereas

any residual hum introduced by the heater circuit

may be balanced out by adjusting a control knob

on the rear panel of the case. Furthermore,

the input sensitivity of the amplifier is relatively low,

so as to keep the preamplifier’s “idle” noise within

inaudible limits. (This design choice has the further

benefit of avoiding the problems of channel

imbalance and sub-optimal frequency response

which often result when the preamplifier’s

potentiometers rest at too low an angle of rotation.)

Also, the mains transformer is mechanically decoupled

from the amplifier case by means of damper units

to prevent residual transformer vibration from

interacting with sensitive parts of the amplifier


Typical for all our mono power amplifiers is

the following no-compromise approach:


Mains transformers, output transformers and filter

chokes are produced in-house to ensure the highest

performance.The output transformers feature tape

wound cut cores (C-cores) and allow for precise

matching of a 4, 8 or 16 ohm load impedance

to the power tube by way of jumpers

soldered to the secondary terminals.

All used rectifier diodes are of

smoothly switching shottky type,

while high grade foil-in-oil

capacitors are used for

the high-tension supply
