- Dimensions (WxHxD): 50cm x 20cm x 42cm
- Weight: 23kg per amplifier
- New price approx.: 20.000€ per pair
Connections
- Number of inputs: 1
- Chinch gold plated: 270kOhm 1,5V eff.
- Number of outputs: 2 (parallel)
- LS-Stereo A: 6 to 14 Ohm automatic adjustment
- LS-Stereo B: 6 to 14 Ohm automatic adjustment
Technical Data
- Continuous power (at distortion factor)
- 10 Ohm: 250W
- Dynamic power
- 8 Ohm:
- 4 Ohm:
- Total harmonic distortion: <0,1%
- Dämpfungsfaktor: >160
- Frequency response: 8Hz - 225kHz -3db
- Signal to noise ratio: >100 db

Special features of tube amplifiers
- Principle: OTL-tube power amplifier
- Tube equipment
6 power tubes
- 3 double triodes
1 pentode
- Transformers: Two power supply transformers and one transformer for the automatic switching circuitry
- High voltage
- Auxiliary voltage/heating
Switch-on electronics: Switch-on is done by an automatic switch, which - and only after the tubes have reached a certain temperature - switches on the high voltage completely noise- and click-free.
Special Features
- Diagnostic socket (service) for checking the internal voltages
- Input connector for switching the power amplifier on and off via AITOS tube preamplifiers
- Led indicators for remote control and fuse fault indication
- A built-in mains phase control
- Three-dimensional wiring
- Anode voltage delay on power up
- Built-in hour meter
Remarks[edit]
Other models in the same series: Aitos OTL power amplifier EV 803 (90 watts).
