PHONO
RIAA EQUALISER STEREO PREAMPLIFIER
The Clarinet's PHONO stereo preamplifier is a three stages active RIAA equaliser circuit using the small signal 12AY7/6072 tube.
The device's gain is 35dB at 47kOhm standard input impedance. It works perfectly with any high-output level MC cartridges or low-level output MC's with an added step-up transformer.
The device is fully hardwired - signal and PSU section - with a special silver-wire and has in-house constructed silver lead out wired resistors on tagboard with silver capacitors and in-house made transformers. The input and output connectors are of the highest-grade pure silver. The case of the device is made of aluminium alloy.
