The PH-1 is a class A single-ended triode phono equalizer. The RIAA equalization curve is derived from a passive RC circuit located between two 6SL7 gain stages. The signal is then direct coupled to a low impedance 12AU7 buffer output stage. The PH-1 is equipped with MM cartridges. Point-to-point wiring, low noise, 1% metal film resistors, polypropylene capacitors, and ceramic sockets are high quality features that make the PH-1 a true high-end phono head amplifier.
