GLIM C-2 Line Preamplifier

The GLIM C-2 line preamplifier is based on a cascode circuit first developed in the golden age of valve amplifiers by MIT professors Valley and Wallman. Further enhancements to the circuit used in this pre-amplifier give lower output impedance and improved linearity. The result is an exceptionally wideband amplifier with low distortion, high definition and excellent headroom.

Construction and technical features

There are only two knobs on the front panel. The left one (as viewed from the front) selects the signal source and the other is a 24-way switched attenuator for setting the level in 2 dB steps.

The preamplifier's power supply features a valve regulator to stabilize the anode voltages. This design practically eliminates hum and reduces the noise level to a minimum. In addition the heater voltage is regulated and adjusted to an optimum value to ensure the longevity of each valve. The life expectation is 10 years.!

Audio performance

This amplifier is designed to satisfy even most stringent requirements of both audiophiles and studio professionals. Typical applications include professional sound monitoring in the technical evaluation of records and CDs. The GLIM C-2 line preamplifier amplifier produces a clean signal which it reproduces at the required level.
