Phono3S

Phono3S is a Switched Input version of Phono3. This kit includes twin inputs which can be configured as MM/MM or MM/MC with individual

cartridge loading for each input. Switching is managed by high quality, gold contact relays on the rear phono sockets, optimising the signal

path and operated via a front panel selector. The MM input can be loaded with parallel resistance and capacitance to suit the particular

requirements of any cartridge. Similarly the MC input, with wide bandwidth transformers, can be optimised with both secondary and primary

loading resistors to match the generator impedance of any MC cartridge. The included MC step-up transformers can be configured as 10:1

or 20:1 gain to match medium or ultra low output cartridges.

RIAA equalisation is handled by two stage passive EQ which features switched High Pass filtering allowing you to choose the Low

Frequency bandwidth suitable for your turntable and speakers. Three position filtering allows flat to infra-bass, 20Hz roll-off or IEC roll-off,

chosen via a front panel selector. Ultra HF EQ is also micro-adjustable, if you have a 'scope, for those who wish to optimise the square wave

response.

As standard this kit comes with the XL pack which includes high performance HT smoothing capacitors, NOS 5751 valves and Soniqs

polypropylene output capacitors for those who desire the ultimate in performance from this outstanding Phono Stage. Units are supplied

configured with one MM and one MC (transformers included) input.

The Phono3S requires a PSU3 power supply

External dimensions with valves: W135 X D314 X H82mm. Weight: 1.6kg

Phono3

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.
