Rated Power:

EL-34 tubes as supplied:

Stereo25 watts wpc. 20 Hz to 20 kHz -3dB. Less than 1% THD+N. 4/8/16 ohms.

50 wpc @ 1 kHz. 8 ohms. Less than .5% THD+N  

Frequency Response:
20 Hz to 20 kHz -3dB @ 8 ohms. 25 watts.

1 watt 20Hz to 20kHz -.3 dB. 
Less than 1.0%
Power Bandwidth:
24 Hz to 25 kHz without filters
Line Inputs:

Source Impedance

1.7 ohms

Input Impedance:
