Specifications
| Frequency response | High level section: ±.5dB, 5Hz to 50kHz, -3db points below 1Hz and above 200 kHz |
|---|---|
| Magnetic Phono: ±.3dB of RIAA, 30Hz to 40kHz | |
| Distortion (THD) | Less than .01% at 2V RMS output |
| Noise & hum | High level: (1) 70 µV RMS maximum residual unweighted wideband noise at main output with gain control minimum (98 dB below 5V RMS output) (2) More than 100dB below 1V RMS input (less than 7 µV equivalent input noise) |
| Phono: 0.12 µV equivalent input noise, IHF weighted, shorted input (78dB below 1mV input) | |
| Gain | Phono input to tape output: 46 dB |
| High level inputs to tape output: 0 dB | |
| Phono input to main output: 66 dB | |
| High level inputs to main output: 20 dB | |
| Input impedance | Line inputs: 50 K ohms |
| Phono: 47K ohms (provisions for any value below 47K ohms or added input capacitance for matching certain magnetic cartridges.) | |
| Output impedance | 250 ohms main output, 1000 ohms recorder output. Recommended load 60K - 100K ohms and 100pF. (20K ohms minimum and 1000pF maximum) |
| Output polarity | |
| Maximum inputs | Magnetic phono, 200mV at 1kHz (1000mV RMS, 10 kHz). High level inputs essentially overload-proof. |
| Rated outputs | 2V RMS 5 Hz to 50 kHz, all outputs; 60K ohm load (main output capability is 50V RMS output at .5% THD at 1kHz into a 100K ohm load with 5V RMS high level input) |
| Power supplies | Electronically-regulated low and high voltage supplies and electronic decoupling. Shielded toroid transformer. Line regulation better than .01%. |
| Tube complement | (1) 6DJ8/ECC88 dual triodes (Hybrid FET/Tube audio circuit, solid-state power supply) |
| Power requirements | 100-135VAC 60Hz (200-270VAC 50/60Hz) 60 Watts |
| Other | |
| Dimensions | 19” (48 cm) W x 5 ¼” (13.4 cm) H (standard rack panel) x 10 ¼” (26 cm) D. Handles extend 1 5/8" (4.1 cm) forward of front panel. Rear chassis fittings extend 7/8" (2.3 cm) |
| Weight | 12 lbs. (5.5kg) Net, 21 lbs. (9.6 kg) Shipping |
