\n
FREQUENCY RESPONSE<\/div>\n
High level section: \u00b1.25dB, 5Hz to 30kHz. -3dB points below 1Hz and above 100kHz. Magnetic phono: \u00b1.25dB of RIAA, 30Hz to 40kHz<\/div>\n<\/div>\n
\n
DISTORTION (THD)<\/div>\n
Harmonic distortion: Less than .01% at 2V RMS output, 20Hz to 20kHz (Typically less than .002% in midband). Intermodulation distortion: Less than .002% at 2V RMS output<\/div>\n<\/div>\n
\n
NOISE & HUM<\/div>\n
High level: (1) 250\u00b5V RMS maximum residual unweighted wideband noise at main output with gain control minimum (86dB below 5V RMS output) (2) More than 90dB below 1V RMS input (less than 20\u00b5V equivalent input noise). Magnetic phono: Approximately .2\u00b5V equivalent input noise, RMS above 1kHz (-94dB reference 10mV input)<\/div>\n<\/div>\n
\n
GAIN<\/div>\n
Magnetic phono input to tape output: 46dB. Magnetic phono input to main output: 72dB. High level inputs to tape output: 0dB. High level inputs to main output: 26dB.<\/div>\n<\/div>\n
\n
INPUT IMPEDANCE<\/div>\n
50K ohms, all high level inputs (2 magnetic phono inputs have front panel selectable impedances of 47K, 10K, 100, 30 and 10 ohms. Also has provision to add to the 40pF input capacitance for matching certain magnetic cartridges.)<\/div>\n
\n
\n
OUTPUT IMPEDANCE<\/div>\n
1000 ohms main output and tape output. Recommended minimum load for maximum audio quality 20K ohms and .001\u00b5F maximum capacitance.<\/div>\n<\/div>\n
\n
OUTPUT POLARITY<\/div>\n
–<\/div>\n<\/div>\n
\n
MAXIMUM INPUTS<\/div>\n
Magnetic phono, 300mV at 1kHz. (900mV RMS, 10kHz) High level inputs essentially overload-proof.<\/div>\n<\/div>\n
\n
RATED OUTPUTS<\/div>\n
2V RMS 5Hz to 30kHz, all outputs; 60K ohm load (main output capability is 60V RMS output at \u00bd% THD at 1kHz into 100K ohm load with 3V RMS high level input)<\/div>\n<\/div>\n
\n
POWER SUPPLIES<\/div>\n
All signal curcuits are powered by electronically regulated power supplies, including vacuum tube heater circuits. Line regulation better than .001% and is effective between 90 and 135 volts RMS (180 and 270 volts for “240” volt units).<\/div>\n<\/div>\n
\n
TUBE COMPLEMENT<\/div>\n
(12) ECC88\/6DJ8, (2) 6L6WGC, (1) 12AT7<\/div>\n<\/div>\n
