Stereo RIAA valve phono-amplifier of exceptional quality. Warm vintage sound, very low THD and sufficient current to drive a pre-amp and another line-level amplifier simultaniously. Requires separate power supplies for low and high voltages

Ready-built PCB requires connectors to be purchased separately and soldered on. See datasheet for details. Valves sold separately.
Ready Built: £69
Bare PCB: £14
Very low-noise stereo head-amp; adds moving-coil capability to ZinAmp's Valve Phono Amplifier. Amplifies the small-signal from a moving-coil phono cartridge to an amplitude suitable for a normal RIAA pre-amp. Selectable gain-levels and input-loadings for your particular MC cartridge.

Reduces unwanted turntable and disc-surface noise by cross-feeding frequncies below 100Hz to mono.

Based on unique research, this filter achives a far superior 18dB/oct, where most other cross-feed filters only achive 6dB/oct and have to begin cross-feeding at a much higher frequency to achieve a similar effect. An 18dB filter is much less intrusive and leaves full stereo separation untouched, whilst adding no unwanted 'flanging' sounds or similar effects.

Requires a split rail DC supply - recommended -15vDC and +15vDC.

Complete power supply for Valve Phono and Pre-amps. Provides 12.6v filament supply and high-voltage rail supply which is adustable between 200 and 320vDC. Twio differnt rail voltages can be supplied and these can be customised with a simple resistor swap. Powered by an 18vDC external 'wall-wart' supply. Can also be powered with a 15v AC transformer with a rectifier.
