For sale is the Marsh p2000t tube hybrid preamp for $699. The preamp uses a pair 5687 tubes. The sale includes an extra pair of Tung Sol 5687, the installed tubes are Raytheon, having 2 different sets provide flexibility to customize the sound to your liking and play into synergistic arrangements with your other components. This preamp is a superior performance tube preamp with triode tube, one of the most linear devices ever developed and designed for the lowest distortion possible. Here it is combined with the FET, creating a new and entirely modern circuit called the “Trans-Mu amplification stage." This brings out all the benefits of the triode tube- extremely low noise, wide frequency response, and low distortion - and eliminates the triode's drawbacks. Each channel uses two triode tubes with a push-pull output for low output impedance. The P2000t is able to drive even the longest cables without music deterioration. The filament voltage is direct voltage through a powerful C-multiplier filter, which ensure the lowest noise and the longest, most reliable operation. How low is low? Dead quiet-so you can hear even the most subtle elements in the music. Marsh-designed capacitors provide great accuracy and high-resolution of details- for the most realistic music reproduction possible and for reliable, long-life performance. Both line amplifiers are fitted with remote 12VDC control for custom installation and easy on/off control of other equipment in the system.

I found it great pairing with SS amps as well as class D amps, had to give it up since the family wants to go with a HT set-up. The unit is in great condition, there is a very light scratch across the face which is hard to see unless at an angle with the right lighting, can’t really see it facing the front. Comes with original box and includes printed manual.
