About the HP100
The Hovland HP-100 is a tube line preamplifier with an optional built-in phono stage, offered in MM and MC configurations. Its line stage uses three vacuum tubes and provides 14dB of voltage gain with a specified frequency response of 10Hz–25kHz (+0/−0.25dB). The optional phono section uses two 12AX7 tubes and one 12AT7 tube; the MC version incorporates a step-up transformer. The unit has multiple line-level inputs, a tape-monitor loop, and line outputs, along with a 31-position, silver-contact stepped attenuator in 2dB increments. It measures 18.25 inches wide by 5.25 inches high by 17.375 inches deep. The HP-100 was a high-end, all-tube preamplifier manufactured by Hovland Company and is discontinued.
