About the SP13 with PH12
The Tubes4HiFi SP13 with PH12 is a custom-built combination of the four-tube SP13 stereo line-stage preamplifier and the PH12 phono circuit installed in one chassis. The standard SP13 is a line-stage-only design with four inputs, one stereo output, remote-control capability, and volume control. SP13/PH12 examples were built to order, with the PH12 adding an RIAA phono input. The SP13 uses four 12AU7 tubes and a simpler power supply than the closely related SP14.
