The C-1 features a low noise solid state preamp followed by two valve stages per channel. The valves are General Electric ECC83/12AX7A types, run from a stabilised 250v DC power supply. The first valve stage acts as a voltage amplifier, with the second stage forming part of the gain control element. The gain control is performed by our own unique transconductance stage which avoids the use of VCAs - thus improving transparency and minimising distortion, which is virtually constant at 0.05% over the full bandwidth. The frequency response of the C-1 is virtually flat between 20Hz and 40kHz, and measured between -3dB points, the C-1's bandwidth is a staggering 5Hz to 70kHz!

The GE tubes have been replaced with vintage Groove Tubes. This is a high-end piece of gear that originally sold for $1500 or so.

I'm looking for $600!
