This unit is in excellent condition - I've been auditioning it, sounds very rich, warm and full. This is a well recognized very simple pre-amp; note this model does not contain the PV 12PH phono stage. Serial number: #2651080; manufacturer's date is 1995 or later.
The PV-12 superseded the PV11. Like its predecessor, it featured zero feedback circuits. For the PV12, critical plate resistors are a special laser-trimmed metal foil type chosen for their extremely low noise and low inductance. The balance control is an eleven-step switch incorporating discrete resistors.
The PV-12L is a line stage version of the PV-12 without the phono section. I purchased this piece to use in my second system. After much listening, I have decided to stay with an integrated amplifier. Makes life easier. I retubed the preamp with a pair of GE 12AU7A tubes, all four sections of the tubes are matched, having been checked with my VTV Dual Triode Characterizer.
