Krohn Hite GPIB Wideband Power Amplifier 7620

Krohn-Hite’s new Model 7620 is a manual or GPIB remote controlled 17/34 watt, wideband power amplifier  that offers extended output power and voltage capabilities, low distortion, and versatility; all at a reasonable cost.
The 7620 provides input modes of A, A–B and –B, common mode rejection of 80dB, input coupling of ac or dc, dc offset control that is variable from 0V to ±200V. A 2-line/20-character display indicates all amplifier settings as well as the status of the heat sink temperature in °C, the output peak voltage, and average output current.
In the non-inverted or inverted mode or operation, the 7620 provides 17 watts of continuous power (34 watts at dc) and 141Vrms from dc to 500kHz. In the balanced mode, the unit provides 34 watts and 800Vp-p. The frequency response is ±0.1dB to 10kHz, and the distortion contributed by the amplifier is <0.01% to 5kHz and<0.3% to 100kHz.
