Frequency response
| ± .5dB, 1Hz to 100Hz, -3dB points below 0.1Hz and above 300kHz |
| Distortion (THD) | Less than .01% at 2V RMS output.(Typically less than .005% in midband) |
| Noise & hum | 20µV RMS residual 1HF weighted noise at main unbalanced output with gain at minimum (100dB below 2V RMS output). Balanced input noise 100dB below 1V input. |
| Gain | Main Output: 18dB (Optional 9dB gain reduction through an internal jumper) |
| | Balanced output: 24dB (Optional 9dB gain reduction through an internal jumper) |
| | Tape output: 0dB |
| Input impedance | 50K ohms unbalanced, 3 megohm balanced. |
| Output impedance | 200 ohms main output. 400 ohms Balanced 1, Balanced 2 (10K ohms minimum load and 2000pF maximum capacitance) |
| Output polarity | |
| Maximum inputs | 20V maximum unbalanced, 8.5V (+21dB) maximum balanced |
| Rated outputs | 2V RMS 1Hz to 100kHz into 60K ohm load (maximum output capability is 30V RMS [60V RMS balanced] output at 05% THD at 1kHz into a 10K ohm load) |
| Power supplies | Electronically-regulated low and high voltage supplies. Two transformers (toroid for high voltage). Line regulation better than .01% |
| Tube complement | (1) 6922 |
