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.

Ready-built PCB requires connectors to be purchased separately and soldered on. See datasheet for details.

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.

Low Voltage Power Supply for use with ZinAmp Valve Phono and Pre Amps

Two outputs of 12.6vDC and two at 7.5vDC. Used to power Heater filaments and a system startup time.

Ready-built PCB requires connectors to be purchased separately and soldered on. See datasheet for details. Heat-sink Mounting Plate also available

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.
Ready Built: £89
Bare PCB: £19
40VA Toroidal Transformer with dual primaries and dual secondary windings for both 12V AC and 220V AC. Specifially designed to run both 12.6V DC and 280v DC supplies for valve phono and preamp modules. Primaries can be wired in parellel for 120v AC or series for 220-240v AC

Manufactured by Airlink Transformers in the UK. CE certified and finished with three turns of Grain Oriented silicon steel to supress stray EMI.

See datasheet for details
Complete: £69
Heavy duty PCB with terminals for AC transformers and connections to power supplies. Terminals are provided for an AC fuse, On/Off switch and auto-power-off switch. Additional terminals for an AC relay and two thermistors form a "soft-start" feature that protects the on/off switch and other circuitry by limiting inrush current. Can be wired for 220v or 120v DC - see datasheet. Switch nets are snubbed to prevent switch-terminal arcing/pitting

Board layout conforms with CE Low Voltage Directive in that primary and secondary AC tracks are appropriately spaced.

Pre-built PCB includes screw terminal blocks as standard. Please email us if you would like different connectors
