I am selling, for pick up only, my very loved Phono Stage.
The unit is mint, I am selling to move into the digital domain.
I am currently running it with NOS 12AU7 RCA as well as NOS Mullard 12AX7 from Brent Jesse. These are available for an additional $75.00.
Tavish Design’s Classic Vacuum-Tube Phono Stage is a passively-equalized, two-gain-stage design whose basic circuit topology has remained popular for more than 55 years. The reason for its endurance is simple: with appropriate updates, it is very difficult to beat without going to elaborate multi-tube circuits. In fact, this simple phono stage outperforms many (if not most) high-end products.
Our update of this classic circuit includes optimized RIAA equalization that makes the circuit less sensitive to variations between tubes, as well as a relay-selected JFET pre-preamplifier for low-output moving coil cartridges. It retains the extremely high overload margin inherent to high-voltage vacuum tube circuits.
Our design also includes linear, regulated high-voltage and heater supplies for low noise and low operating drift. The 200 volt supply rail operates the tubes in their intended range - we don’t starve the tubes by operating them at low voltages. And, we completely avoid the use of switching power supplies. The unit is powered from an external AC wall transformer, using a small internal step-up transformer for the high voltage supply. This puts the larger, high-current transformer outside (and well away from) the enclosure. A sophisticated circuit board design with multiple ground domains eliminates coupled noise. Finally, we use a low-noise 5751 input tube (you can substitute a 12AX7 if you prefer). The result of all this is exceptionally low noise and hum for a tube phono stage, in a compact and low-cost package.
Vinyl LPs sound better than ever, and Tavish Design’s Classic Vacuum-Tube Phono Stage lets you get the most out of your LPs for a reasonable price. It’s not your grandfather’s phono stage - it offers high-end sound and performance, and exceptional value.
