The Phono3 is an all valve phono stage which matches a wide variety of turntables and cartridges. This standard module utilises all passive RIAA equalisation over two gain stages to offer unparalleled accuracy and freedom from the slew rate limiting of common loop feedback EQ stages.

The input can be configured for MM or MC cartridges, the latter via optional wide bandwidth MC step-up transformers. which can provide 10:1 or 20:1 voltage gain to match a wide range of cartridges.  Ultra HF EQ is also micro-adjustable, if you have a ‘scope, for those who wish to optimise the square wave response.

The upgrade XL option includes high performance HT smoothing capacitors, JJ ECC83S valves and Soniqs polypropylene output capacitors for those who want the ultimate in performance.

The Phono3 requires a PSU3 power supply. PSU3 is sold separately.

Phono3 is available either as a kit or pre-built.
