Trichord Dino Mk2 Phonostage

The Dino, from the small UK design and manufacturing company Trichord Research, has been a very successful and multi award winning phono stage. We have a nice good condition Mk2 example complete with a power supply. Cosmetically some marking to the acrylic surface which is difficult to see in the photographs, but this does not impinge on the unit’s performance. It will be professionally packaged and comes with our standard three month warranty.
Trichord Research Say….
High Value MM/MC Phono Stage
Selectable capacitance loading (MM/MC)
Selectable cartridge resistance loading (four settings)
Selectable gain switching (five settings)
Trichord Dino MK2 Phonostage – the latest incarnation of a product which pretty much changed the market in sub £500 phono stages. Loads of flexibility means the Dino will cope with pretty much whatever you throw at it. The Dino is user adjustable with 2 sets of four DIP switches on the underside of the unit for ease of access. These switches allow for adjustment of cartridge loading and gain setting. The circuitry is signal non-inverting and constructed using high performance, audio grade bipolar and JFET operational amplifiers, metal oxide resistors and ultra-low impedance capacitors throughout for lowest possible noise. The RIAA equalisation network is fully passive and located between two active gain stages. The capacitors and resistors used in this stage are very close tolerance audiophile types. Two state of the art ultra-low impedance, low noise wide-band voltage regulators are employed to power both channels and are largely responsible for the high sonic performance of the Dino.
